Block diagram of long recoil operation cycle. Long recoil operation is found primarily in shotguns, particularly ones based on John Browning's Auto-5 action. In 1885 a locked breech, long recoil action was patented by the Britons Schlund and Arthur. [9] In a long recoil action, the barrel and bolt remain locked together during recoil ...
Short Recoil Lock from Walther P38. Locked breech is the design of a breech-reloading firearm's action. This is important in understanding how a self-reloading firearm works. In the simplest terms, the locked breech is one way to slow down the opening of the breech of a self-reloading firearm when fired. The source of power for the movement is ...
The recoil operation is a type of locked-breech action used in semi-automatic and fully automatic firearms. It also uses energy from the combustion in the chamber acting directly on the bolt through the cartridge head, but in this case the firearm has a reciprocating barrel and breech assembly, combined with a bolt that locks to the breech.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

It is chambered in the DJP-201 7.62×51mm cartridge, [1] [4] and features an unusual open-bolt, hybrid long stroke, short recoil operation. The QJY-201 incorporates weight reduction features, such as lightweight material for the body and a detachable box magazine made of fabric, reducing its weight.
Unlike the P22, which the PK380 is based on, the PK380 does not operate by blowback where pressure generated by a firing cartridge is countered by a combination of the inertial weight of the slide assembly and the force of the recoil spring. Instead, the PK380 employs a Browning-type, tilt barrel design referred to as "a locked breech short ...
Caliber/calibre: In small arms, the internal diameter of a firearm's barrel or a cartridge's bullet, usually expressed in millimeters or hundredths of an inch; in measuring rifled barrels this may be measured across the lands (.303 British) or grooves (.308 Winchester) or; a specific cartridge for which a firearm is chambered, such as .45 ACP or .357 Magnum.
From left to right: 9×19mm Parabellum (pistol cartridge) 7.92×33mm Kurz (intermediate-power rifle cartridge) 7.92×57mm Mauser (full-power rifle cartridge). A fully powered cartridge, also called full-power cartridge or full-size cartridge, is an umbrella term describing any rifle cartridge that emphasizes ballistic performance and single-shot accuracy, with little or no thought to its ...
