.357 SIG ammunition propels 125- to 147-grain bullets at muzzle velocities of 1,250–1,450 fps, generating 400–550 ft-lbs of energy for a flat trajectory and deep penetration with manageable recoil. Full metal jacket (FMJ) loads deliver smooth feeding and consistent accuracy for range sessions, while jacketed hollow point (JHP) rounds are engineered for controlled expansion in self-defense or duty applications. Chambered in compact duty pistols like the SIG P229, Glock 31 and H&K P2000, .357 SIG cartridges provide law-enforcement performance in service-sized handguns.
