40 S&W Ammo

Favored by law enforcement agencies, military personnel, and civilian shooters, the .40 S&W cartridge is one of the most popular handgun and submachine gun cartridges in the world. Debuted in January 1990, the .40 S&W is a rimless pistol cartridge, developed jointly by American firearms manufacturers Smith & Wesson and Winchester under a contract with the Federal Bureau of Investigation (FBI) to replace the standard-issue .38 Spl revolver cartridge. The .40 S&W was designed to duplicate the ballistic performance of the FBI’s low-velocity 10mm Auto cartridge while fitting into medium-frame semi-automatic handguns, similar in size and weight to the Glock® 19.

At GunMag Warehouse, we offer a large selection of target and defensive .40 S&W ammo at an affordable price. Shop our full collection today and save big on your next trip to the range.
