In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder. [3]
Most modern firearms are designed to not be capable of firing when significantly out-of-battery. As such, a firearm that is out-of-battery typically cannot be fired, which is why this is a type of firearm malfunction. A dangerous situation can occur when a chambered round fires when the firearm is out-of-battery (called an out-of-battery ...
The S&W Model 61 is a blowback-operated pistol chambered in .22 Long Rifle based upon the Bayard 1908 (Pieper Bayard) pistol. It was marketed for self-defense to fill a void in the pocket auto market after the banning of the importation of small, concealable handguns.
Rebated-rim cartridges are known to be used on firearms using advanced primer ignition (API blowback) for its operation, notably autocannons such as the 20 mm Becker/Oerlikon series. [1] API blowback firearms have straight-sided chamber walls as possible (and sometimes slightly bottlenecked) to contain the cartridge and allow a deeper chambering.
Schematic of an Advanced Primer Ignition blowback operation that works in a similar way to slamfire by striking the cartridge as its moving forward before it is fully chambered. A slamfire is a discharge of a firearm occurring as a cartridge is being loaded into the chamber .
An alternative design concept for recoil-operated firearms is the inertia operated system, the first practical use of it being the Sjögren shotgun, developed by Carl Axel Theodor Sjögren in the early 1900s, a Swedish engineer who was awarded a number of patents for his inertia operated design between 1900 and 1908 and sold about 5,000 ...
