A shotgun is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which usually discharges numerous small pellet-like spherical sub-projectiles called shot, or sometimes a single solid projectile called a slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs are also available.
A grenade launcher is a weapon that fires a specially designed, large-caliber projectile, often with an explosive, smoke, or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces.
The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher that fires a 40×46mm grenade, which uses what the US Army calls the High-Low Propulsion System to keep recoil forces low, and first appeared during the Vietnam War. Its distinctive report has earned it colorful nicknames, such as "Thumper", "Thump-Gun", "Bloop Tube", "Big Ed", "Elephant Gun," and "Blooper" among American soldiers as well as "Can Cannon" in reference to the grenade size; Australian units referred to it as the "Wombat Gun". The M79 can fire a wide variety of 40 mm rounds, including explosive, anti-personnel, smoke, buckshot, flechette, and illumination. While largely replaced by the M203, the M79 has remained in service in many units worldwide in niche roles.
A combat shotgun is a shotgun issued by militaries for warfare. The earliest shotguns specifically designed for combat were the trench guns or trench shotguns issued in World War I. While limited in range, the multiple projectiles typically used in a shotgun shell provide increased hit probability unmatched by other small arms.
The KS-23 is a Soviet shotgun, although because it uses a rifled barrel it is officially designated by the Russian military as a carbine. KS stands for Karabin Spetsialniy, "Special Carbine". It is renowned for its large caliber, firing a 23 mm round, equating to 6.27 gauge using the British and American standards of shotgun gauges and approximately 4 gauge using the current European standards, making it the largest-bore shotgun in use today.
In current usage, a riot gun or less-lethal launcher is a type of firearm used to fire "non-lethal" or "less-lethal" ammunition for the purpose of suppressing riots or apprehending suspects with minimal harm or risk. 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 shotguns and 37mm or 40 mm grenade launchers.
A riot shotgun is a shotgun designed or modified for use as a primarily defensive weapon, by the use of a short barrel and sometimes a larger magazine capacity than shotguns marketed for hunting. The riot shotgun is used by military personnel for guard duty and was at one time used for riot control, and is commonly used as a door breaching and patrol weapon by law enforcement personnel, as well as a home defense weapon by civilians. Guns of this type are often labeled as breaching shotguns, tactical shotguns or special-purpose shotguns to denote the larger scope of their use; however, these are largely marketing terms.
40 mm grenade is a generic class-name for grenade launcher ammunition in 40 mm (1.57 in) caliber. The generic name stems from the fact that several countries have developed or adopted grenade launchers in 40 mm caliber.
The BXP is a 9×19mm submachine gun developed by Andries Piek, with the fully automatic version finalised in 1978, and the semi-automatic version for civilians coming later in 1984. Due to an international arms embargo against South Africa, South Africans designed and manufactured some weapons as a small firearms industry developed locally. The BXP was one of these locally designed and developed firearms, and is considered the final stage of development of the line of hand machine carbines that started with the LDP in Rhodesia and the Kommando in South Africa. Produced originally by the South African company Milkor (Pty) Ltd, its name 'BXP' stands for 'Blowback eXperimental Parabellum', hinting both at its operating mechanism as well as its caliber. The original automatic version of the BXP was intended for use by South African law enforcement, including the South African Police, the Correctional Services, and the specialised airport security unit based at the then Jan Smuts International Airport, Johannesburg.
The United States Armed Forces has created a plethora of different types of 40 mm grenades in both the low-velocity 40×46mm and high-velocity 40×53mm calibers which uses what it calls a high-low propulsion system which keeps recoil forces within the boundaries of an infantry weapon. Presented on this page is a basic overview.
The MAG-7 is a pump-action shotgun manufactured by Techno Arms PTY of South Africa since 1995.
37 mm flare or "1.5 inch" caliber is the specification for a common launching system for non-lethal and less-lethal ammunition. Such launchers are also often known as "gas guns" due to their original use by police for launching tear gas projectiles. 37 mm systems are typically smoothbore as rifling is unnecessary or even detrimental to the performance of the usual projectiles.
The Neopup PAW-20 is a 20×42mm semi-automatic grenade launcher designed by Tony Neophytou and as of 2015, is produced and marketed by Denel.
The HK69A1 is a 40 mm grenade launcher developed and produced by the German arms manufacturer Heckler & Koch (H&K). The weapon was designed to engage enemy troops and strongpoints out to a distance of 350 m; it can also be used to deploy smoke grenades and illumination flares.
Milkor (Pty) Ltd is a privately owned South African company established in 1980. The company is best known for the range of Milkor MGLs 40mm, used in more than 50 countries. Since 2017 Milkor has expanded their capabilities to include Land, Air and Sea.
The Milkor MGL is a lightweight 40 mm six-shot revolver-type grenade launcher developed and manufactured in South Africa by Milkor (Pty) Ltd. The MGL was demonstrated as a concept to the South African Defence Force (SADF) in 1981. The MGL was then officially accepted into service with the SADF as the Y2. After its introduction in 1983, the MGL was gradually adopted by the armed forces and law enforcement organizations of over 50 countries. Total production since 1983 has been more than 50,000 units.
The Federal Riot Gun (FRG) is a firearm made by Federal Laboratories Inc., designed to fire non-lethal munitions. Its ammunition includes 37 and 38mm baton and tear gas rounds. The baton rounds were cylindrical, rubber projectiles.
The Milkor 40mm UBGL grenade launcher is a lightweight single-shot, underslung grenade launcher designed and developed in South Africa by Milkor (Pty) Ltd. It can be attached to most modern assault weapons and rifles using a Picatinny rail system. The UBGL is capable of firing standard 40mm rounds including illumination and observation rounds. Clip-on, clip-off mechanism allows the UBGL to be fitted, with an additional recoil buffer, to any weapon fitted with a Picatinny rail.
The RGP-40 is Polish six-shot revolver-type 40mm grenade launcher designed by WAT and OBR SM Tarnów and produced by ZM Tarnów. Its design is heavily influenced by the M32 MGL.
The RGS-50M is a smoothbore single-shot break-action Russian 50 mm (2.0 in) grenade launcher manufactured by Degtyarev Plant.
