A submachine gun, abbreviated SMG, is a magazine-fed, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
The Blish lock is a breech locking mechanism designed by John Bell Blish based upon his assumption that under extreme pressures, certain dissimilar metals would resist movement with a force greater than friction laws would predict. In modern engineering terminology, it is an extreme manifestation of what is now called static friction, or stiction. His locking mechanism was used first in the Thompson submachine gun. Nowadays it is discredited as a useful firearm operating principle, due to its almost nonexistent effects on the operation and functioning of a firearm; because of that, firearms which theoretically employed it operate not by the supposed Blish lock principle, but, in fact, by blowback operation.
The Thompson submachine gun is a blowback-operated, air-cooled, magazine-fed selective-fire submachine gun, invented by the United States Army Brigadier general John T. Thompson in 1918. It was originally designed to break the stalemate of trench warfare of World War I, but was not finished until after the war ended.

The .45 Reising submachine gun was manufactured by Harrington & Richardson (H&R) Arms Company in Worcester, Massachusetts, USA, and was designed and patented by Eugene Reising in 1940. The three versions of the weapon were the Model 50, the folding stock Model 55, and the semiautomatic Model 60 rifle. Over 100,000 Reisings were ordered during World War II, and were initially used by the United States Navy, Marine Corps, and the United States Coast Guard, though some were shipped to Canadian, Soviet, and other allied forces to fight the Axis powers.

The Hyde-Inland M2 was a United States submachine gun design submitted for trials at Aberdeen Proving Ground in February 1941. Work was undertaken by General Motors Inland Manufacturing Division to develop workable prototypes of George Hyde's design patented in 1935. The model first submitted for trials in April 1942 was designated the Hyde-Inland 1. Trials revealed the design was superior to the M1 submachine gun in mud and dirt tests, and its accuracy in full-automatic firing was better than any other submachine gun tested at the time. An improved Hyde-Inland 2 was designated U.S. Submachine gun, Caliber .45, M2 as a substitute standard for the M1 Thompson in April 1942. As Inland's manufacturing capacity became focused on M1 carbine production, the US Army contracted M2 production to Marlin Firearms in July 1942. Marlin began production in May 1943. Marlin's production failed to match the trials prototype performance; and Marlin's original contract for 164,450 M2s was canceled in 1943 upon adoption of the M3 submachine gun. The M2 is chambered for the .45 ACP cartridge and used the same 20- or 30-round magazine as the Thompson. Its cyclic rate of fire is 570 rounds per minute. None of the approximately 400 manufactured were issued by any branches of the United States military.
The Owen gun, known officially as the Owen machine carbine, was an Australian submachine gun designed by Evelyn Owen in 1938. The Owen was the only entirely Australian-designed and constructed service submachine gun of World War II and was used by the Australian Army from 1942 until 1971.
The machine gun is a type of automatic firearm. Colloquially the term may refer to the broader category of automatic firearms.

The term Chicago piano has been used as a nickname for a number of weapons:
A drum magazine is a type of high-capacity magazine for firearms. Cylindrical in shape, drum magazines store rounds in a spiral around the center of the magazine, facing the direction of the barrel. Drum magazines are contrasted with more common box-type magazines, which have a lower capacity and store rounds flat. The capacity of drum magazines varies, but is generally between 50 and 100 rounds.
Firearm magazines are used "jungle style" if they are fixed together side by side, often with tape. The spare magazine may be pointing downwards in relation to the one fitted to the weapon.
The M3 is an American .45-caliber submachine gun adopted for the U.S. Army service on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to produce and lighter, although, contrary to popular belief, it was less accurate. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser", owing to its visual similarity to the mechanic's tool.

Auto-Ordnance is a U.S. arms development firm founded by retired Colonel John T. Thompson of the U.S. Army Ordnance Department in 1916. Auto-Ordnance is best known for the Thompson submachine gun, used as a military weapon by the Allied forces in World War II, and also notorious as a gangster weapon used during the Roaring Twenties.

Tommy Gun: How General Thompson's Submachine Gun Wrote History is a non-fiction book written by San Francisco author Bill Yenne in 2009. The book traces the history of the Thompson submachine gun, also known as the Tommy gun, through its usage in warfare, organised crime, and subsequently, its presence in film and television, as an "immortal icon."
