Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
The Glock 43 is the first Glock pistol to be manufactured with a single-stack 9×19mm Parabellum magazine, having a standard capacity of six rounds and being unique to the model. Unlike other subcompact Glock pistols, the Glock 43 cannot use factory magazines from its larger relatives due to its single-stack magazine design.
The .45 GAP (Glock Auto Pistol) or .45 Glock (11.43×19mmRB) is a pistol cartridge designed by Ernest Durham, an engineer with CCI/Speer, at the request of firearms manufacturer Glock to provide a cartridge that would equal the power of the .45 ACP, have a stronger case head to reduce the possibility of case neck blowouts, and be shorter to fit in a more compact handgun.
Nevertheless, "perceived" recoil limits vary from shooter to shooter, depending on body size, the use of recoil padding, individual pain tolerance, the weight of the firearm, and whether recoil buffering systems and muzzle devices (muzzle brake or suppressor) are employed. For this reason, establishing recoil safety standards for small arms ...
Locked recoil systems rely on timing to allow safe operation. A very heavy bolt mechanism can be used (such as in sub-machineguns) to slow the rate of movement and reduce the rate of fire. [5] This is not adequate with higher velocity and higher energy cartridges. Rifles and most handguns use locked breech designs to control recoil safely.
Some short-recoil–operated firearms, such as the German MG 42 and MG 3, use a mechanism at the muzzle to extract some energy from the escaping powder gases to push the barrel backwards, in addition to the recoil energy. This boost provides higher rates of fire and/or more reliable operation.
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy ( E t ) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f ) for non-SI units of measure.
Although the low power of the .380 ACP does not require a locking mechanism, there have been a number of locked-breech pistols chambered in .380 ACP, such as the Remington Model 51, Kel-Tec P3AT and Glock 42; all three being designed to be lighter than blowback-operated .380 ACP weapons.
