1122-652: The bolt-action service rifles then in use (such as the American M1903 Springfield ). Thompson came across a patent issued to the American inventor John Bell Blish in 1915, while searching for a way to allow his weapon to operate safely without the complexity of a recoil or gas-operated reloading mechanism. Blish's design (then known as the Blish lock ) was based on the supposed adhesion of inclined metal surfaces under pressure. Thompson gained financial backing from
1188-416: The "L" 50-round drum and "XX" 20-round box magazines were tested 6 December 1941, at Fort Knox, Kentucky . An extended thirty-round box magazine and a forty-round magazine, which were made by welding two 20-round magazines face to face, jungle style, were tested. The testers considered both superior to either the "XX" box or "L" drum. The 30-round box was approved as the new standard in December 1941 to replace
1254-729: The "XX" and "L" magazines. (The concept of welding two box magazines face-to-face was also carried over to the M42 submachine gun.) The staff of Savage Arms looked for ways to simplify the M1928A1, and produced a prototype in February 1942, which was tested at Aberdeen Proving Ground in March 1942. Army Ordnance approved adoption (as the M1) in April 1942. M1s were made by Savage Arms and by Auto-Ordnance . M1s were issued with

The Thompson was first used in combat in 13 June 1921, when West Virginia state troopers fired on the mountainside near Lick Creek, where striking miners were firing at passing cars. By the time of the Battle of Blair Mountain , 37 had been acquired by the West Virginia state police and 56 were in the hands of coal companies and local law enforcement. The guns were also shipped to various hardware stores in

The Thompson was also used by U.S. and overseas law enforcement and police forces, most prominently by the FBI . The FBI used Thompsons until they were declared obsolete and ordered destroyed in the early 1970s. Because of their quality and craftsmanship, as well as their gangster-era and WWII connections, Thompsons are sought as collector's items. There were fewer than 40 pre-production prototypes.

In the European theater,

In 1928, Federal Laboratories took over distribution of the weapon from Thompson's Auto-Ordnance Corporation. The new cost
1650-481: The Korean War, US troops were surprised to encounter communist Chinese troops armed with Thompsons (amongst other captured US-made Nationalist Chinese and American firearms), especially during unexpected night-time assaults which became a prominent Chinese combat tactic in the conflict. The gun's ability to deliver large quantities of short-range automatic assault fire proved very useful in both defense and assault during
1716-506: The M1928A1 units had complaints of the "L" 50-round drum magazine. The British Army criticized "the [magazine's] excessive weight, [and] the rattling sound they made" and shipped thousands back to the U.S. in exchange for 20-round box magazines. The Thompson had to be cocked, bolt retracted, ready to fire, in order to attach the drum magazine. The drum magazine also attached and detached by sliding sideways, which made magazine changes slow and cumbersome. They also created difficulty when clearing
1782-500: The M3/M3A1 never replaced the Thompson, and purchases continued until February 1944. Though the M3 was considerably cheaper to produce, at the end of World War II, the Thompson, with a total wartime production of over 1.5 million, outnumbered the M3/M3A1 submachine guns in service by nearly three to one. Thompson submachine guns were used by both sides during the 1948 Arab-Israeli war . Following
1848-472: The Model of 1921. It was available to civilians, but, because of the weapon's high price, initially saw poor sales. The Thompson (with one Type XX 20 round "stick" magazine) had been priced at $ 200 in 1921 (roughly equivalent to $ 3,416 in 2023) The major initial complaints concerning the Thompson were its cumbersome weight, its inaccuracy at ranges over 50 yards (46 m), and its lack of penetrating power using
1914-594: The Model of 1928. The Thompson saw popularity as a point-defense weapon for countering ambushes by Nicaraguan guerrillas (in the Banana Wars ) and led to the creation of four-man fire teams which had as much firepower as a nine-man rifle squad. Federal sales were then followed by sales to police departments in the US, as well as to various international armies and constabulary forces; chiefly in Central and South America. In 1926,

The Thompson was soon found to have limited effect in heavy jungle cover, where the low- velocity .45 bullet would not penetrate most small-diameter trees or protective armor vests. (In 1923, the Army had rejected the .45 Remington–Thompson , which had twice the energy of the .45 ACP.) In the U.S. Army, many Pacific War jungle patrols were originally equipped with Thompsons in

The FBI had also acquired Thompsons in 1933 following the Kansas City Massacre . A number of these guns were acquired by a construction company in Brazil, after construction of
2178-572: The Thompson was the first weapon to be labeled and marketed as a "submachine gun". Thompson intended for the weapon to provide a high volume of automatic, man-portable fire for use in trench warfare—a role for which the Browning Automatic Rifle (BAR) had been determined ill-suited. The concept had already been developed by German troops using their own Bergmann MP 18 (the world's first submachine gun) in concert with their Sturmtruppen tactics. The first Thompson entered production as
2244-461: The Thompson was the only submachine gun available to the Australian Army for most of the vital Kokoda Track campaign in 1942. It became so prized that soldiers routinely picked up Thompson guns dropped by killed or wounded comrades. However, the weight of the ammunition and difficulties in supply eventually led to its replacement in Australian Army units in 1943 by Australian-made submachine guns,

This was possibly the first engagement where submachine guns were used on both sides. The Thompson achieved early notoriety in the hands of Prohibition and Great Depression -era gangsters and the lawmen who pursued them. It

The box magazine tripped the bolt open lock when empty, facilitating magazine changes. An empty box was easy to reload with loose rounds. However, users complained that it was limited in capacity.

The Thompson was primarily developed in Cleveland, Ohio . Its principal designers were Theodore H. Eickhoff, Oscar V. Payne, and George E. Goll. By late 1917, the limits of the Blish lock were discovered (which is essentially an extreme manifestation of static friction ), and, rather than

Compared to more modern submachine guns, the Thompson is quite heavy, weighing roughly the same as the contemporary M1 Garand semi-automatic rifle, and requires a lot of cleaning. This was one of the major complaints about the weapon by U.S. Army personnel to whom it

Many Chinese Thompsons were captured and placed into service with American soldiers and marines for the remaining period of the war.

However, due to unforeseen production delays and requests for modifications,

3036-596: The gun was widely utilized in British and Canadian commando units, as well as in the U.S. Army paratrooper and Ranger battalions , where it was issued more frequently than in line infantry units because of its high rate of fire and its stopping power, which made it very effective in the kinds of close combat these special operations troops were expected to undertake. Military Police were fond of it, as were paratroopers, who "borrowed" Thompsons from members of mortar squads for use on patrols behind enemy lines. The gun

These weapons were loaned to the United States Marine Corps which was, at that time, tasked with guarding mail shipments; this prompted the US Navy to formally test the Thompson. The Navy requested a reduction in the rate of fire. Auto-Ordnance complied, modifying the weapons by adding a substantial amount of mass to the actuator. In 1927 a number of Thompsons would be shipped to Marines in China and Nicaragua . The Navy subsequently ordered 500 guns, designated

Although the drum magazine provided significant firepower, in military service it was found to be overly heavy and bulky, especially when slung on the shoulder while marching.
