The .40 S&W (10×22mm Smith & Wesson) is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson and Winchester. The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9mm size) automatic handguns. It uses .40 inch (10.16mm) diameter bullets ranging in weight from 105 to 200 grains (6.80 g to 13 g).

The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9mm size) automatic handguns. It uses .40 inch (10.16mm) diameter bullets ranging in weight from 105 to 200 grains (6.80 g to 13 g).
- In the aftermath of the 1986 FBI Miami shootout, the FBI started the process of testing 9mm and .45 ACP ammunition in preparation to replace its standard issue revolver with a semi-automatic pistol. The semi-automatic pistol offered two advantages over the revolver: 1) it offered increased ammunition capacity, and 2) it was easier to reload during a firefight. The FBI was satisfied with the performance of its .38 Special +P L.S.W.C.H.P. (lead semi-wadcutter hollowpoint) cartridge ("FBI Load") based on decades of dependable performance. Ammunition for the new semi-automatic pistol had to deliver terminal performance equal or superior to the .38 Special FBI Load. The FBI developed a series of practically oriented tests involving eight test events that reasonably represented the kinds of situ
- The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the FBI's reduced velocity 10mm cartridge which could be retrofitted into medium-frame (9mm size) automatic handguns. In other words, the middle ground between 10mm and 9mm. It uses .40-inch (10.16 mm) diameter bullets ranging in mass from 135 to 200 grains (9 - 13g). A number of loads with hollow point bullets offer a good combination of expansion, penetration, and temporary cavitation.
