The '''M1 Carbine''' (formally the '''United States Carbine, Caliber .30, M1''') is a lightweight [[Semi-automatic firearm|semi-automatic]] [[carbine]] that became a standard firearm in the U.S. military during World War II and the Korean War, and was produced in several variants. It was widely used by U.S. and foreign military and paramilitary forces, and has also been a popular civilian firearm.

In [[selective fire]] versions capable of [[Automatic firearm|fully-automatic]] fire, the carbine is designated the '''M2 Carbine'''. The '''M3 Carbine''' was an M2 with an active [[infrared scope]] system.

==History==                         
[[Image:Saginaw-M1.jpg|thumb|250px|left|A Saginaw M1 carbine, made in Grand Rapids, Michigan, used by Marines in the Pacific Theater in World War II]]
The United States Army's [[M1 Garand rifle]] was originally developed to chamber a lighter .276 [[Cartridge|round]], but this design feature was canceled in the early 1930s. The M1 rifle would eventually be chambered for the same powerful [[.30-06 Springfield]] standard round used in other service weapons of the time, such as the [[M1903 Springfield rifle|Springfield M1903]], the [[M1918 Browning Automatic Rifle|BAR]], and the [[M1917 Browning machine gun|M1917]]/[[M1919 Browning machine gun|M1919]] [[machine gun]]s. This left the Army without the lighter, handier rifle it had wanted. This, along with lessons learned during earlier wars, observations of conflicts during the 1930s, and dissatisfaction with existing [[submachine gun]]s and rifles contributed to the development of the M1 Carbine.

Troops in rear areas, paratroopers, or front-line troops required to carry other equipment (such as medics, engineers and [[mortar]] crews) found the full-size rifles too cumbersome, and [[pistol]]s and [[revolver]]s to be insufficiently accurate or powerful. Submachine guns such as the [[Thompson submachine gun|Thompson]] were more than sufficiently powerful for close-range encounters, but lacked effective range and were not significantly easier to carry or maintain than the existing service rifles (such as the M1903 and Garand).

The same considerations applied to airborne infantry, a concept that was also under consideration at the time. Prior to the development and issue of submachine guns such as the [[M3 submachine gun|M3 "Grease Gun"]], a submachine gun like the Thompson was also much more expensive than pistols and most rifles of the period. The .30-06 Garand, then entering service, was as heavy and cumbersome as the existing service rifles. It was decided that a new weapon was needed for these other roles. While the range of a pistol is about 50 yards and the range of existing rifles was several hundred yards, the requirement for the new firearm called for a maximum range of 300 yards.

A carbine version of the standard-issue semi-automatic rifle was considered, but the .30-06 round for which the M1 Garand was chambered was found to be too powerful. The requirement was for a weapon lighter and handier than the Garand, with less recoil, but at the same time, greater range, accuracy, and effective [[stopping power]] than the [[M1911 Colt pistol|M1911A1]] pistols currently in use. The M1 Carbine was intended for use by soldiers who required a more compact, lightweight defensive weapon, and for soldiers who did not utilize an infantry rifle as their primary arm.

In 1938, the Chief of Infantry requested the Ordnance Department develop a lightweight rifle or carbine, though the formal requirement for the weapon type was not approved until 1940. This led to a competition in 1941 by major U.S. firearm companies and designers. [[Winchester Repeating Arms Company|Winchester]] at first did not submit a design, being too busy perfecting the Winchester Military Rifle in .30-06. The rifle originated as a design by Jonathan "Ed" Browning, half-brother of the famous weapons designer [[John Browning]]. A couple of months after Ed Browning's death in May 1939, Winchester hired ex-convict [[David Marshall Williams|David M. "Carbine" Williams]], a some-time bootlegger who had devised a short-stroke gas piston design while serving a prison sentence for murder. (This unlikely but true story, a natural for the movie industry, was the basis of the 1952 movie ''Carbine Williams'' starring James Stewart.) Winchester hoped Williams would be able to complete various designs left unfinished by Ed Browning. Williams' first design change for the rifle was the incorporation of his short-stroke piston design. After the Marine Corps semi-automatic rifle trials in [[1940]], Browning's rear-locking tilting bolt design was considered to be unreliable in sandy conditions. As a result, the rifle was redesigned yet again to incorporate a Garand-style [[rotating bolt]] and operating rod.

The prototypes for the US M1 carbine were chambered for a new cartridge, the .30 M1. It chambers the [[.30 Carbine]], a smaller and lighter .30 caliber ([[7.62 mm caliber|7.62mm]]) cartridge, very different, in both design and performance, from the larger .30-'06 used in the Garand.

The .30 Carbine cartridge was intermediate in both [[muzzle energy]] (''ME'') and [[muzzle velocity]] (''MV'').  It is essentially a rimless version of the obsolete [[.32 Winchester Self-Loading]] cartridge. The .30 Carbine had a round-nose 110 gr (7.1 g) bullet, in contrast to the [[Spitzer bullet|spitzer]] bullet designs found in most full-power rifle cartridges of the day. From the M1 Carbine's 18 in (460 mm) [[Gun barrel|barrel]], the .30 Carbine cartridge produced a muzzle velocity of approximately 1,970 ft/s (600 m/s), a velocity between that of contemporary submachine guns (approximately 900 to 1,600 ft/s (300–500 m/s)) and full-power rifles and [[light machine gun]]s (approximately 2,400 to 2,800 ft/s (700–900 m/s)). For example, the U.S. M3 submachinegun, chambered in [[.45 ACP]], had an MV of 920 ft/s (280 m/s); the British [[Bren]] light machine gun in [[.303 British]] reached 2,440 ft/s (740 m/s); the M1 Garand firing .30-'06 had an MV of 2,800 ft/s (850 m/s). At the M1 Carbine's maximum listed range of 300 yards (270 m), its bullet has about the same energy as pistol rounds like the [[7mm Nambu]] do at the muzzle. Bullet drop is significant past 200 yards (180 m).

By May 1941, the rifle prototype had been shaved to a mere 7.5 lb (3.4 kg). Winchester contacted the Ordnance Department to examine their design, who believed the design could be scaled down to a carbine which weighed 4.5 to 4.75 lb (2.0–2.2 kg). In response, Major René Studler demanded a carbine prototype as soon as possible. The first model was developed in 13 days by William C. Roemer and Fred Humeston. It was cobbled together using the trigger housing and lockwork of a Winchester M1905 rifle. The prototype was an immediate hit with Army observers.

After the initial Army testing in August 1941, Winchester set out to develop a more refined version. This competed successfully against other carbine candidates in [[September 1941]], and Winchester was notified of their victory the very next month. Standardization as the M1 Carbine was approved in [[October 22]], 1941. Contrary to popular myth, Williams had little to do with the carbine's development, with the exception of his short-stroke gas piston design. As a matter of fact, Williams went about creating his own design apart from the other Winchester staff. Williams' final carbine design was not ready for testing until December 1941, two months after the Winchester M1 Carbine had been adopted and type-classified. None of William's additional design features were incorporated into later M1 production.

The M1 carbine was designed primarily to offer non-combat and line-of-communications troops a better defensive weapon than a pistol or submachine gun, with greater accuracy and range, but without the recoil, cost, or weight of a full-power infantry rifle. The carbine was also easier for less experienced soldiers and smaller-framed people to fire than the .30 caliber infantry rifles of the day. The carbine was more convenient to carry for officers, NCOs]], or specialists encumbered with weapons, field glasses, radios, or other gear. Tankers, drivers, artillery crews, mortar crews, and other personnel were also issued the M1 carbine in lieu of the larger, heavier Garand. Belatedly, a folding-stock version of the M1 carbine was developed, after a request was made for a compact and light infantry arm for airborne troops. The first M1 carbines were delivered in mid-1942, with initial priority given to troops in the European Theater of Operations.

The M1 and its reduced-power .30 cartridge were never intended to serve as a primary infantry weapon, nor was it comparable to more powerful assault rifles developed late in the war. Nevertheless, the carbine was soon issued to infantry officers, machine-gun crews, paratroopers, and other frontline soldiers. Its reputation in combat was mixed. Some infantrymen and Marines, especially those who did not use a rifle as their primary weapon, preferred the carbine over the Garand because of the weapon's small size and light weight. The carbine also gained generally high praise from airborne troops who were issued the folding-stock M1A1. The carbine's exclusive use of non-corrosive primered ammunition was found to be a godsend by troops and ordnance personnel serving in the Pacific, where barrel corrosion was a significant issue, though not to the same extent in Europe, where some soldiers reported misfires attributed to bad primers.

In the Pacific theatre, soldiers and guerrilla forces operating in heavy jungle with only occasional enemy contact generally praised the carbine for its light weight and accuracy. Other soldiers and Marines engaged in frequent daily combat (particularly those serving in the Philippines) found the weapon to have insufficient stopping power and penetration. Reports of Japanese soldiers being shot multiple times in chest and body without immediate effect began to surface. Like the .45 Thompson, some troops found the .30 Carbine cartridge incapable of penetrating small trees and other light jungle cover. Aware of these shortcomings, the U.S. Army, its Pacific Command Ordnance staff, and the Aberdeen small arms facility continued to work on shortened versions of the Garand throughout the war, though none were ever officially adopted.

Initially, the M1 Carbine was intended to have a selective-fire capability, but the decision was made to put the M1 into production without this feature. Fully-automatic capability was incorporated into the design of the M2 (an improved, selective-fire version of the M1), introduced in [[1944]].

The M2 Carbine continued in use during the Korean War. As noted, the M2 featured a selective-fire switch allowing optional fully-automatic fire at a rather high rate (850-900 rpm) and a 30-round magazine. In Korea, all versions of the M1/M2 carbine soon acquired a poor reputation for jamming in extreme cold weather conditions, eventually traced to inadequate recoil impulse and weak return springs. A [[1951]] official U.S. Army evaluation noted the weapon's cold-weather shortcomings, and recorded complaints by troops for failure to stop heavily-clothed North Korean and Chinese troops at close range after multiple hits.

The M2 carbine was again issued to some U.S. troops in Vietnam, particularly reconnaissance units (LRRP) and advisors as a substitute standard weapon. These weapons began to be replaced by the [[M16 rifle|M16]] in the late 1960s, and many M1, M2, and M3 Carbines were given to the South Vietnamese.

The M1/M2 carbine was finally replaced by the M16 in the mid-1960s. The M1/M2/M3 carbines were the most heavily produced family of U.S. military weapons for several decades, most of these being the M1 version.

==Performance==
[[Image:Infantry anti-tank crew fires on Nazis.jpg|thumb|right|250px|A U.S. anti-tank crew in combat in the Netherlands, November 4, 1944. The soldier on the far right is holding an M1 Carbine]]

The M1 carbine bolt mechanism is similar to the [[M1 Garand rifle]], though the carbine has a different gas system and trigger mechanism design. The gas system is a lightweight tappet-and-slide [[Gas-operated|gas system]]. Initially fed from a 15 round [[magazine]], a 30 round magazine was introduced for the M2.

One characteristic of .30 Carbine ammunition is that from the beginning of production, non-corrosive primers were specified. This was the first major use of this type of primers in a military firearm. Because the rifle had a closed gas system, not normally disassembled, corrosive primers would have led to a rapid deterioration of the gas system. The use of non-corrosive primers was a novelty to service ammunition at this time.  Some misfires were reported in early lots of .30 M1 carbine ammunition, attributed to moisture ingress of the non-corrosive primer compound.

The very first carbines, those made before mid-[[1943]], were originally equipped with a "V-cut" extractor for removal of the fired round from the chamber. The "V-cut" design was found to be flawed and unreliable. In the field "V-cut" extractors were reground to a straight configuration, which enhanced reliability, until factory production was able to supply the better design. 

Reports of insufficient power have been reported with the M1 carbine during its period of military service, though the carbine was not designed for offensive use. The M1 had a high practical [[rate of fire]]. This, and its light weight, compactness, and low recoil, made it a convenient self-defense weapon. With a much-reduced kick compared to the Garand, a soldier would be able to fire multiple aimed shots more rapidly.

The .30 Carbine round is typically a 110 gr (7.1 g) bullet with a muzzle velocity of 1,970 ft/s (600 m/s) giving it 880 ft·lbf (1,190 J) of energy. In comparison, a [[.357 Magnum]] revolver fires the same weight [[bullet]] at about 1,300 ft/s (400 m/s) for about 410 ft·lbf (560 J) of energy, though the .357 is of larger diameter, and often equipped with a [[Soft point bullet|soft-point]] or [[hollowpoint]] bullet.<ref>[http://www.winchester.com/ Winchester Ammunition]</ref> Nevertheless, reports of the carbine's failure to stop enemy soldiers continue to figure in individual after-action reports, postwar evaluations, and service histories of the U.S. Army and Marine Corps. Recent evaluations of the .30 Carbine cartridge indicate it is in fact an effective penetrator.<ref>[http://www.theboxotruth.com/docs/bot36.htm The Box O' Truth #36 - Frozen Clothing And The Box O' Truth - Page 1]</ref>

Later analysis of negative reports about the carbine and its round have postulated many failures to stop were in fact due to rounds failing to actually hit the target. Early versions of the carbine had poor sights, and when fired, the ammunition loses considerable lethality after 200 yards (180 m). However, with improved sights and used within the limitations of the cartridge, the carbine became a much more formidable weapon.

Categorizing the M1 carbine series has been the subject of much debate. The M1 is sufficiently accurate at short ranges. At 100 yards (91 m), it can deliver groups of between 3 and 5 minutes of angle, sufficient for its intended purpose as a close-range defensive weapon. Its muzzle energy and range are beyond those of any submachine gun of the period, though its bullet is much lighter in weight and smaller in diameter than .45 caliber weapons, and much less powerful than those of other [[service rifle]]s of the period.

The classification of the M2 and M3 is also a controversial subject. The M1 and later M2 carbine was never designed to be an assault rifle, in league with the later German [[Sturmgewehr 44|StG44]] and Russian [[AK-47]], and the .30 Carbine gives up significant muzzle velocity (roughly 350 ft/s (110 m/s)) to both. Additionally, the bullets used in the cartridges of the AK-47 and StG44 are [[Spitzer bullet|spitzer]] designs, and suffer less energy loss and trajectory drop at distances beyond 100 yards. Most authorities list the effective combat range of the M1 Carbine at around 200 yards, compared to 250-300 yards (230–270 m) for the AK-47 and StG44.

===Attachments===
The M1 carbine was used with the [[M8 grenade launcher]], which was fired with the M6 cartridge. It also accepts the [[M4 bayonet]], which formed the basis for the later [[M6 bayonet|M6]] and [[M7 bayonet]]-knives.

During World War II, the T23 [[Flash suppressor|flash hider]] was also developed, which could greatly reduce muzzle flash; it was developed from an earlier model for the Garand.

The M3 carbine was initially used with the M1 sniper scope ("[[Image intensifier#Generation_0|Snooperscope]]"), which was an active infrared system. Before the M3 carbine and M1 sniper scope were type-classified, they were known as the T3 and T120, respectively. The system continued to be developed, and by the time of the Korean War, it was used with the M3 sniper scope. Eventually, the scopes would be superseded by passive infrared scopes. All the M1 attachments would fade out of U.S. military service during the 1960s, when the M1 carbine would be replaced by the 5.56 mm firearms — the M16 and its carbine variants, such as the [[Colt Commando|XM177/CAR-15]]. Many of the attachments continued to be used with other countries that also used the M1, such as South Vietnam and [[Israel]].

==Production and usage==
[[Image:Carbine-iwo-jima-194502.jpg|thumb|left|200px|A United States Marine equipped with an M1 Carbine in the Battle of Iwo Jima, February 1945. An M8 grenade launcher can be seen attached to the muzzle of the weapon]]

A total of 6.25 million M1 carbines of various models were manufactured, making it the most produced small arm in [[United States|American]] military history. Despite being designed by Winchester, the great majority of these were made by other companies. The largest producer was the Inland division of General Motors, but many others were made by contractors as diverse as IBM, the Underwood typewriter company, and the Rock-Ola jukebox company. Standard Products models were the fewest produced, at a little over 4,000. Many carbines were refurbished at several arsenals after the war, with many parts interchanged from original maker carbines. True untouched war production carbines, therefore, are the most collectible.<ref>[http://www.fulton-armory.com/M1Carbine.htm "A Pocket History of the M1 Carbine" - Fulton Armory]</ref>

The German designation for captured carbines was '''Selbstladekarabiner 455(a)'''. The "(a)" came from the country name in [[German]]; in this case, ''Amerika''.

The SAS used the M1 & M1A1 carbines after 1943. The weapon was taken into use simply because a decision had been taken by Allied authorities to supply .30 caliber weapons from US stocks in the weapons containers dropped to Resistance groups sponsored by an SOE, or later also OSS, organizer, on the assumption the groups so supplied would be operating in areas within the operational boundaries of U.S. forces committed to Operation OVERLORD. They were found to be suited to the kind of operation the two British, two French, and one Belgian Regiment carried out. It was handy enough to parachute with, and, in addition, could be easily stowed in an operational Jeep. Other specialist intelligence collection units, such as 30 Assault Unit sponsored by the Naval Intelligence Division of the British Admiralty, which operated across the entire Allied area of operations, also made use of this weapon.

A variant was produced shortly after WWII by the Japanese manufacturer Howa Machinery, under U.S. supervision. These were issued to all branches of the Japan Self-Defense Forces, and large numbers of them found their way to Southeast Asia during the Vietnam War.

Numerous examples were obtained and used by the Israeli Palmach-based special forces in the 1948 Arab-Israeli War. Because of their compact size and semi-auto capabilities, they were given to reconnaissance companies of the Israeli Defence Forces.

It was also used by police and border guard in Bavaria after WWII and into the 1950s. The carbines were stamped according to the branch they were in service with; for instance, those used by the border guard were stamped "''Bundesgrenzschutz''" (English: Federal Border Guard). Some of these weapons were modified with different sights, finishes, and sometimes new barrels.

After the Korean War, the carbine was widely exported to U.S. allies and client states (such as South Korea, Taiwan, ROC and other European allies), and was used as a frontline weapon well into the Vietnam era. The M1 carbine was also issued to the Korean and Israeli military and police forces.

The M1A was also used by the French Paratroopers (such as the 1er RCP) during the Algerian War from 1954 to 1962.

==Current military use==
The Israeli police still uses the M1 Carbine as a standard long gun for non-combat elements and MASHAZ volunteers. During the late 1990s, the police started to issue a Micro [[IMI Galil|Galil]] variant called the ''Magal'' chambered in .30 Carbine, but after extensive problems with various malfunctions, they withdrew the weapon from service in [[2001]]. Today, non-combat police units are equipped with Micro Galils chambered in 5.56mm and M1 and M1A1 carbines.

In Rio de Janeiro, [[Brazil]], a police battalion named BOPE (''Batalhão de Operações Policiais Especiais'', or "Special Police Operations Battalion") still uses the M1 carbine.

The government of the [[Philippines]] still issues M1 carbines (together with M1 Garands, M14s, and M16s) to the Civilian Auxiliary Forces Geographical Unit or (CAFGU) and Civilian Volunteer Organization (CVO).

==Commercial copies==
Several companies manufactured copies of the M1 Carbine after World War II, which varied in quality. Some companies used a combination of original USGI and new commercial parts, while others manufactured entire firearms from new parts, which may or may not be of the same quality as the originals. These copies were marketed to the general public and were not made for or used by the U.S. military.

[[Image:M1 carbine kahr.jpg|thumb|left|250px|An Auto-Ordnance AOM-130 Carbine manufactured in 2007.]]
In [[1963]], firearms designer and promoter Melvin M. Johnson introduced a version of the M1 Carbine called the "Spitfire", which fired a 5.7mm (.22in) [[wildcat cartridge]] known as the [[wildcat cartridge#Example wildcat cartridges|5.7 mm MMJ]] or .22 Spitfire.<ref>The Spitfire fired a 40-grain (2.6 g) bullet with a muzzle velocity of 2850 ft/s (870 m/s) for a muzzle energy of 720 foot-pounds force (980 J). Barnes, Frank C. ''Cartridges of the World'' (DBI, 1978), p.127.</ref> Johnson promoted the smaller caliber and the modified carbine as a survival rifle for use in jungles or other remote areas. While the concept had some military application when used for this role in the selective-fire M2 Carbine, it was not pursued and few Spitfire carbines were made.<ref>Barnes, 1989 edition.</ref>

The Auto-Ordnance division of Kahr Arms began production of an M1 Carbine replica in [[2005]]. Auto Ordnance had produced various replacement parts for IBM during World War II, but did not manufacture complete carbines until the introduction of this replica.  The AOM110 and AOM120 models (no longer produced) featured birch stocks and handguards, [[Parkerizing|Parkerized]] receivers, flip-style rear sights and barrel bands without bayonet lugs.  The current AOM130 and AOM140 models are identical except for American walnut stocks and handguards.<ref>[http://www.auto-ordnance.com/ao_aom110_f.html "Auto-Ordnance M1 Carbines" - Auto-Ordnance.com]</ref> <ref>[http://www.nrapublications.org/tar/M1Carbine.asp "M1 Carbine" - American Rifleman]</ref>

*Universal - Early Universal guns were, like other manufacturers, assembled from USGI parts. However, beginning in 1968, the company began producing the "New Carbine", which externally resembled the M1 but was in fact a completely new firearm internally, using a different receiver, bolt carrier, bolt, recoil spring assembly, etc. with almost no interchangeability with USGI carbines.<ref>[http://www.bavarianm1carbines.com/carbine_universal.html "Universal Firearms Corporation" - bavarianm1carbines.com]</ref>

==Hunting and civilian use==
The M1 carbine is still in use today by many civilian shooters and police around the world. .30 Carbine is used for a number of types of hunting, including white-tailed deer. The ease of use and great adaptability of the weapon led to it being used by Malcolm X (as a self defense tool) and Patty Hearst (as a bank robbery implement). Both were featured in famous photographs carrying the M1 carbine.  The .30 Carbine cartridge is definitely underpowered for larger North American game such as elk, moose, and bear. Some U.S. states prohibit use of the .30 Carbine round for hunting deer and larger animals due to a lessened chance of killing an animal in a single shot, even with expanding bullets. It is prohibited in several states such as Pennsylvania<ref>[http://www.pgc.state.pa.us/pgc/cwp/view.asp?a=465&q=151336 Pennsylvania Game Commission - State Wildlife Management Agency: Deer Hunting Laws and Regulations]</ref> because of the semi-automatic function, and Illinois<ref>[http://dnr.state.il.us/admin/systems/Digest/Digest.pdf Illinois: Digest of Hunting and Trapping Regulations 2007-2008, "Statewide Deer Hunting Information", Illinois Department of Natural Resources,  p. 11.]</ref> which prohibits all non-muzzleloading rifles for big game hunting.
