40 S&W AND 45 ACP

“forty ess-and-double-ew” “forty-five aye-see-pea”

The .40 S&W cartridge possesses nearly identical accuracy, drift, and drop as the 9mm Parabellum while having an energy advantage over it. These more energetic loads can also create a hydrostatic shock in targets.

The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power.

The .40 Smith and Wesson is a rimless pistol cartridge developed from scratch for law enforcement to duplicate the performance of the FBI’s reduced velocity 10mm Auto cartridges which could be retrofitted into medium frame semi-automatic handguns.

The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power. The cartridge also has relatively low muzzle blast and flash, as well as moderate recoil. The standard issue military .45 ACP round has a 230 grain bullet that travels at approximately 830 feet per second when fired from the government issue M1911A1 pistol and approximately 950 feet per second from the M1A1 Thompson sub-machine gun. The cartridge also comes in various specialty rounds of varying weights and performance levels. It operates at a relatively low maximum chamber pressure rating of 21,000 psi (145 MPa) (compared to 35,000 psi/241 MPa for 9mm Parabellum and .40 S&W, 37,500 psi/259 MPa for 10mm Auto, 40,000 psi/276 MPa for .357 SIG), which due to a low bolt thrust helps extend service life of firearms in which it is used. The drawbacks for military use include the cartridge’s large size, weight, increased material costs in comparison to the smaller, flatter shooting NATO standard 9×19mm Parabellum cartridge, which uses less powder, brass and lead per round.
