Buffalo Bore loads its .357 SIG (load no. 25A20) to the pressure the cartridge was actually designed for, driving a 125-grain jacketed hollow point at roughly 1,425 feet per second out of a 4-inch carry barrel instead of the watered-down velocity many factory loads settle for. Buffalo Bore Ammunition calls this a full-power load because that is exactly what it is, built for shooters who chose .357 SIG specifically for its velocity advantage over 9mm and .40 S&W. The hollow point bullet is tuned to expand at that velocity, converting the cartridge’s speed into a wide, fast-opening wound channel. Flash-suppressed powder protects the shooter’s vision if the pistol has to fire in low light, a real consideration since most defensive shootings happen after dark. For a carrier who picked .357 SIG for a reason, this is the load that actually delivers what the caliber promises.
