A gun without a shoulder stock or one that would normally be considered to commonly have a shoulder stock. A short barreled shotgun with a pistol grip instead of a shoulder stock would fit into the latter category.

Short for Thompson Sub Machine Gun. A full auto gun (though you can buy semiautomatic replicas) which fired the 45 caliber Colt Automatic Pistol (ACP round). It was the gun that many gangsters were shown to use in the movies. Historical research shows that most gangsters in the thirties also relied on handguns. The Thompson was heavy, bulky, and not all that concealable. Plus, compared to handguns at that time, the Thompson was rather spendy, and most small time punks running numbers games, moonshine, etc. couldn't afford them or chose not to. Still, they were used by some gangsters and the G men. That's what led to the 1934 NFA which forced registration and taxes on those guns. That didn't curb crime, however. The lifting of prohibition...

after the 1934 NFA,there were still a lot of machine guns in civilian ownership,unregistered. Owners just kept a low profile,kept the guns disassembled.

not until the 1968 GCA offered a brief 30 day "amnesty" for registration,then closed registration off permanently were most of those guns registered and made "legal".

that was because in 1934,the $200 "tax" was equal to or more than the cost of the firearm itself. with inflation,the $200 tax is a pittance these days,and the NFA-registered,legal guns are $10K or more in value.

but a new full-auto AK-47 can be had outside the US today for under $200.

A November 2012 Mass Shootings Analysis report issued by the New Jersey Intelligence & Analysis Unit (NJ ROIC) in partnership with the U.S. Department of Homeland Security shows semiautomatic handguns are the most common weapons used to carry out mass shootings. The report was issued one month before the Newtown shooting in which, according to the coroner and police, the killer used a semi-automatic rifle.
