The "Foster slug", invented by Karl M. Foster in 1931, and patented in 1947 (U.S. patent 2,414,863), is a type of shotgun slug designed to be fired through a smoothbore shotgun barrel, even though it commonly labeled as a "rifled" slug. A rifled slug is for smooth bores and a sabot slug is for rifled barrels.
Most non-shotshell loads, such as less lethal ammunition like bean bags, are made only in 12-gauge. However, 20-gauge and .410 shotguns in riot gun configuration are available. Smaller bores are popular for home defense, as the reduced power and recoil make them more suitable for less experienced shooters who may be more recoil-sensitive.
The shorter barrel makes the weapon easier to maneuver around corners and in tight spaces, though slightly longer barrels are sometimes used outdoors for a tighter spread pattern or increased accuracy of slug projectiles. Home-defense and law enforcement shotguns are usually chambered for 12-gauge shells, providing maximum shot power and the ...
The AA-12 (Auto Assault - 12), originally designed and known as the Atchisson Assault Shotgun, is a fully automatic combat shotgun developed in 1972 by Maxwell Atchisson. . However, the original development by Atchisson seems to have produced only a few guns at prototype-level, with the development that ultimately led to the gun entering the market being done later by Military Police Systems ...
A 20-gauge buckshot load would most commonly be utilized in close- to mid-range self-defense scenarios. [citation needed] While slug loads are ballistically less accurate than rounds used in rifles, powerful, high-grain slug loads can provide improved ballistics for hunting deer when paired with a rifled barrel.

Shotgun slugs are currently under consideration by the US military as an anti-materiel round; the tendency of typical commercial shotgun slugs to deform on impact would render them illegal under the Hague Convention of 1899 and so a jacketed, hardened or sabot slug may be adopted. Less lethal rounds are used by U.S. troops serving as police ...
Less-lethal launchers may be special purpose firearms designed for riot control use, or standard firearms, usually shotguns and grenade launchers, adapted for riot control use with appropriate ammunition. The ammunition is most commonly found in 12 gauge (18.5 mm/.729 inch) shotguns and 37mm (1.46 inch) or 40 mm (1.57 inch) grenade launchers.
The FRAG-12 is a specialized 12-gauge shotgun shell which contains a small amount of high explosive to breach intermediate barriers, defeat light armored vehicles, and disrupt IEDs. [1] The shell was designed by the Special Cartridge Company in London, England. Later its patent extended to Olympic Technologies Ltd in Gibraltar. [2]
