The GLOCK 31’s .357 SIG cartridge delivers high velocity and energy transfer by necking down a 10mm case to hold a .355″ projectile. This design provides a flatter trajectory and reliable barrier penetration, making it a respected choice for law enforcement. The pistol’s locked-breech, short-recoil operation and striker-fired mechanism ensure consistent ignition and cycling under demanding conditions.
