About .40 S&W Ammunition
.40 S&W was developed for the FBI to bridge the gap between 9mm capacity and .45 ACP power, and it served as the dominant U.S. police cartridge for years. It delivers more energy than 9mm with snappier recoil, and a surplus of former duty pistols keeps it popular and affordable. Bulk .40 S&W FMJ range ammo usually runs $0.30 to $0.42 per round.
