A recoilless rifle (RCLR) or recoilless gun is a type of lightweight tube artillery that is designed to allow some of the propellant gases to escape out the rear of the weapon at the moment of ignition, creating forward thrust that counteracts some of the weapon's recoil.lder recoilless rifles are still used by the U.S. National Park Service and the U.S. Forest Service as a system for avalanche control. The Washington State Department of Transportation uses a 105 mm recoilless rifle for avalanche control on Interstate 90.
The .380 ACP cartridge (also called a 9mm Browning) was introduced in 1908 by Colt as a self defense weapon. The .380 ACP cartridge is rimless and straight-walled. The 9mm (9Ã19mm Parabellum) cartridge was introduced in 1902 by German weapons manufacturer DWM for their Luger semi-automatic pistol.
