I tried everything. The whole dang thing turns. Couldn't even break the barrel loose. Man are these things screwed on I'm frustrated. Doug Richardson?? Any help appreciatedThe Thompson submachine gun is an American submachine gun first invented by John T. Thompson in during World War I and became infamous during the Prohibition era, being a signature weapon of various organized crime syndicates in the United States.

It was a common sight in the media of the time, being used by both law enforcement officers and criminals. The Thompson was favored by soldiers, criminals, police, FBI, and civilians alike for its fully automatic fire, while still being relatively lightweight, portable and easy to use.

It has since gained popularity among civilian collectors for its historical significance. It has considerable significance in popular culture, especially in works about the Prohibition era and World War II, and is one of the most well known and recognised firearms in history. The original fully automatic Thompsons are no longer produced, but numerous semi-automatic civilian versions are still being manufactured by Auto-Ordnance.

These retain a similar appearance to the original models, but they have various modifications in order to comply with US firearm laws. General John T. Thompson developed the Thompson Submachine Gun.

He originally envisioned an " auto rifle " semi-automatic rifle to replace the bolt action service rifles then in use, such as the American M Springfieldbut he came across a patent issued to John Bell Blish in 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 was based on the adhesion of inclined metal surfaces under pressure. Ryan and started the Auto-Ordnance Company in for the purpose of developing his "auto rifle". It was primarily developed in Cleveland, Ohio[24] and the principal designers were Theodore H. Eickhoff, Oscar V. Payne, and George E. By latethe limits of the Blish Principle were discovered; rather than working as a locked breech, it functioned as a friction-delayed blowback action.

It was found that the only cartridge currently in service that was suitable for use with the lock was the. Thompson then envisioned a "one-man, hand-held machine gun" in. Payne designed the gun and its stick and drum magazines. The project was then titled "Annihilator I", and most of the design issues had been resolved by ; however, the war ended two days before prototypes could be shipped to Europe.

At an Auto-Ordnance board meeting in to discuss the marketing of the "Annihilator", with the war now over, the weapon was officially renamed the "Thompson Submachine Gun". While other weapons had been developed shortly prior with similar objectives in mind, the Thompson was the first weapon to be labeled and marketed as a "submachine gun".

The Thompson first entered production as the M M Thompsons were sold in small quantities to the United States Postal Inspection Service [28] to protect the mail from a spate of robberies [29] and to the United States Marine Corps. Federal sales were followed by sales to several police departments in the US and minor international sales to various armies and constabulary forces, chiefly in Central and South America.

It was popular as a point-defense weapon for countering ambush by Nicaraguan guerrillas, and led to the organization of four-man fire teams with as much firepower as a nine-man rifle squad. The remainder made their way to the Irish Republican Army by way of Liverpool and were used in the last month of the Irish War of Independence — They were not found to be very effective in Ireland; the Thompson caused serious casualties in only percent of the actions in which it was used.

The Thompson achieved most of its early notoriety in the hands of Prohibition and Great Depression -era gangsters, the lawmen who pursued them, and in Hollywood films about their exploits, most notably in the St Valentine's Day Massacre. The two Thompson guns used in the massacre are still held by the Berrien County Sheriff's Department. Inthe Cutts Compensator a muzzle brake was offered as an option for the M; Thompsons with the compensator were cataloged as No.

Nationalist China acquired a quantity for use against Japanese land forces, and eventually began producing copies of the Thompson in small quantities for use by its armies and militias. Inthe Thompson submachine gun was adopted by the U. Over 1. Military users of the MA1 had complaints about the "L" fifty-round drum magazine; the British Army officially criticised "their excessive weight, the rattling sound they made" and shipped thousands back to the U.

The Thompson had to be cocked, bolt retracted ready to fire, to attach the drum. It attached and detached by sliding sideways, which made magazine changes slow and also created difficulty in clearing a cartridge malfunction "jam".Originally conceived during World War I as a portable machine gun to break the stalemate of trench warfare, the Thompson entered production in and was primarily marketed for law enforcement purposes.

The Thompson's extensive use by gangsters during the Prohibition era and by Allied troops during World War II cemented the gun's image into popular culture; consequently, it has become of the most recognizable guns in history. By the end ofshortcomings of the Blish lock were found, and it had been discovered that the only cartridge currently in U.

The project was then titled Annihilator Iand bymost of the design issues had been resolved. On 11 Novemberthe Annihilator prototypes were put into crates, sent to the docks in New York and were attempted to be sent to Allied troops in Europe; however, the war ended the same day just a few hours later and as such were never actually sent to Europe.

As a result of this, the Annihilator s remained in said crates and the docks for weeks on end until they were brought back to the factory. Officially renamed the Thompson submachine gun in at an Auto-Ordnance board meeting, the Thompson was the first weapon to be marketed as a submachine gun despite there having been weapons being made with a similar purpose in the recent past.

The Thompson entered production in and was marketed to both militaries, civilians and similar agencies, though its high price resulted in few sales. M Thompsons were first sold in small quantities to the U.

Post Office in an attempt to protect the mail from a spate of robberies, followed by adoption by several police departments in the United States and minor international sales to various armies and constabulary forces located mainly in Central and South America. The Thompson achieved most of its fame and notoriety in the hands of Prohibition and Depression-era gangsters, as well as its portrayal in in Hollywood films. Nationalist China also acquired a number of Thompsons for use against Japanese land forces; this eventually led them to produce copies or derivatives of the Thompson for their own use by its various armies and militias.

Soon, John T. Thompson decided to sell his gun to the public, stating it was the just the gun for home defense. The Thompsons could be bought at hardware stores and even through the mail. Production, however, remained slow until the onset of World War II, at which point Thompsons were being produced in significantly larger quantities.

Inthe Thompson was the only submachine gun in production outside of Europe, and as a result the British, French and Swedish governments hurriedly placed orders for these guns. Other Allied countries purchased the Thompson as well, notably the United Kingdom and France; however, the French never got the chance to use them to their full potential as France lost to Germany in just a few weeks.

Modifications to simplify production and reduce cost were made inresulting in the M1 and M1A1 models, commonly carried by both non-commissioned and commissioned officers. Thompson had intended his weapon to be used as a trench-clearing weapon to quickly sweep trenches and clear out enemies; this concept was later adopted by the Germans where this technique was used in tandem with Sturmtruppen lit.

The Thompson found particular utility during World War II in Allied hands as a weapon for use by patrol leaders, non-commissioned officers, scouts and similar units. The Thompson was a common sight in the European Theater, being used by British and Canadian commando units and American ranger battalions and paratroopers; the paratroopers liked the Thompson and used it to great effect by "borrowing" these Thompsons from members of mortar squads for use on patrols and similar missions.

In the Pacific Theater, most Commonwealth forces like the Australian Army initially used the Thompson extensively in jungle patrols and ambushes; however, due to its weight, the weapon was eventually replaced by similar weapons like the Owen gun and Austen The U. Marines also used the Thompson in limited numbers, where it was a common sight during their later island assaults.

The Thompson was soon found to be ineffective in heavy jungle cover, as the low-velocity. Thompsons were also a common sight in the early phases of the New Guinea and Guadalcanal campaigns where they were used for jungle patrols by American forces, but they ended up being replaced by the Browning Automatic Rifle to fulfil the same purpose.

The Thompson was rendered thoroughly obsolete by the beginning of World War II as many European nations had developed cheaper, simpler and equally effective weapons; however, they remained in use and were used to great effect. By the time of the Korean War, the Thompson had been retracted from service as a standard-issue submachine gun with American forces and was replaced by the M3 submachine gun and the M1 carbine in that role.

The M3 submachine gun's supposed role was to apparently have it slowly drafted into service and to have it produced in large enough a number to replace the Thompson and have the latter retracted from frontline service; this never happened though as the Thompson was never really replaced by the M3 due to constant requests for modifications and unforeseen production delays of the M3. Due to this, the number of Thompsons in active service amounted to three times the amount of M3s in service by the end of World War II.

Many Thompsons were later distributed to Chinese armed forces as a form of military aid before Chiang Kai-shek's government fell to Mao Zedong's communist regime in Many American troops were surprised to see the amount of Thompsons in use by these Chinese communist forces during the Korean War, especially during nighttime ambushes. Many of these weapons were later recaptured and placed back into service with American soldiers and Marines for the rest of the war.

The Thompson also saw limited service with the U. Marine Corps carrying over from their Post Office service as the M in a series of interventions in Central America particularly Nicaraguawhere it was used to counter ambushes by guerrilla forces.

Some forces were also armed with Thompsons during the Vietnam War, but the weapons were quickly replaced by the M The Thompson was also used by U. The FBI first acquired Thompsons in in response to the Kansas City Massacre and used them untilat which point they were declared wholly obsolete.Jump to content.

Dan, I recently had my a1 short barreled and it was most certainly more enjoyable with the shorter barrel. Indeed the wait time is 6 months from the time my form 1 went pending to the date on the approved stamp it was 6 months to the day.

Posted 10 August - PM. The difference in handling really surprised me, and both guns make a lot more sense with the properly shortened barrels. As for wait time on the tax stamp these days, I just received stamps for a suppressor and my full auto Thompson A1. Both took just over 8 months to clear, unfortunately. Two years ago when I had my semi-auto Thompsons SBR'd, the wait time was 6 months, almost to the day. For me, the barrel change makes both guns a lot more fun to handle and use, and it just makes them look right.

I had one installed in each Thompson when they were SBR'd. They are both a whole lot easier and more fun to use at the range now with the new spring kits installed. Posted 14 August - PM. I did the SBR change only to make the gun look "right", as it was meant to be; I did it myself in my shop, as the barrel only screws in.

Posted 15 August - AM. Do it. The end result more than compensates for the red tape. These guns just don't look or feel right with those squirrel gun barrels. And you will turn heads at the range. Posted 17 August - PM. Posted 10 September - PM.

Community Forum Software by IP.A submachine gunabbreviated SMGis a magazine -fed, automatic carbine designed to shoot handgun cartridges.

The term "submachine gun" was coined by John T. Thompsonthe inventor of the Thompson submachine gun[1] to describe its design concept as an automatic firearm with comparatively much inferior firepower hence "sub-" than a proper machine gun. The submachine gun was developed during World War I — as close quarter offensive weapons, mainly for trench raiding. At its peak during World War II —millions of SMGs were made for use by regular troopsclandestine commandos and partisans alike. After the war, new SMG designs appeared frequently.

The Germans also experimented with machine pistols by converting pistols such as the Mauser C96 and Luger P from semi-automatic to fully automatic operation and adding detachable stocks. Carbine-type automatic weapons firing pistol rounds were developed during the latter stages of World War I by Italy, Germany and the United States. Their improved firepower and portability offered an advantage in trench warfare. Inthe Italians introduced the Villar-Perosa aircraft machine gun.

It fired pistol-caliber 9mm Glisenti ammunition, but was not a true submachine gun, as it was originally designed as a mounted weapon. Both the OVP and the Beretta had a traditional wooden stock, a round top-fed box magazineand had a cyclic rate of fire of rounds per minute. The Germans initially used heavier versions of the P08 pistol equipped with a detachable stock, larger-capacity snail- drum magazine and a longer barrel.

This weapon used the same round snail-drum magazine as the Luger P The MP 18 was used in significant numbers by German stormtroopers employing infiltration tacticsachieving some notable successes in the final year of the war.

However, these were not enough to prevent Germany's collapse in November However, the war ended before prototypes could be shipped to Europe. However, the FBI and other U. Eventually, the submachine gun was gradually accepted by many military organizations, especially as World War II loomed, with many countries developing their own designs.

Changes in design accelerated during the war, with the trend being one of the abandonment of complex and finely made pre-war designs like the Thompson submachine gun to weapons designed for cheap mass-production and easy replacement like the M3 Grease Gun.

The Italians were among the first to develop submachine guns during World War I. The 38 was made in a successive series of improved and simplified models all sharing the same basic layout. The Beretta has two triggers, the front for semi-auto and rear for full-auto. Most models use standard wooden stocks, although some models were fitted with an MPstyle under-folding stock and are commonly mistaken for the German SMG.

The 38 series was extremely robust and proved very popular with both Axis forces and Allied troops who used captured Berettas. The 38 series is the longest serving of the world's SMGs, as later models can still be seen in the hands of Italian military and police forces.

However, the MP38 production was still just starting and only a few thousand were in service at the time. It proved to be far more practical and effective in close quarters combat than the standard-issue German Kar 98K bolt-action rifle.

From it, the simplified and modernized MP40 commonly and erroneously referred to as Schmeisser was developed and made in large numbers; about a million were made during World War II. The MP40 was lighter than the MP It also used more stamped parts, making it faster and cheaper to produce.

The Suomi was used in combat until the end of the Lapland warwas widely exported [9] and remained in service to the late s.

Inthe Russians introduced the 7. The PPSh's round drum magazine is a copy of the Suomi's. Later in the war they developed the even more readily mass-produced PPS submachine gun - all firing the same small but high-powered Tokarev cartridges.

Thus, the Soviet Union could field huge numbers of submachine guns against the Wehrmacht, with whole infantry battalions being armed with little else.What today is arguably the largest dealer in surplus war material in the country, Sarco an acronym for Steen Armament Research CompanyInc.
