DoubleTap Handgun Ammunition Features DoubleTap Ammunition builds this .357 Sig load around a 125 grain bonded jacketed hollow point bullet a design intended to maintain structural integrity through clothing and other barriers while still achieving reliable expansion. The bonding process fuses the jacket to the lead core reducing the chance of fragmentation and helping the bullet retain weight for deeper more consistent penetration. This combination of controlled expansion and weight retention is specifically suited to personal defense scenarios where barrier performance matters. A brass case provides reliable extraction and consistent chamber pressures across the 20 round box. Loaded specifically for personal defense applications this .357 Sig round is intended to deliver dependable stopping power from compact and full size pistols chambered in the cartridge. DoubleTap positions its ammunition toward shooters who prioritize terminal performance over economy making this load a suitable choice for daily carry rather than high volume training. The 20 round box size keeps the ammunition practical for carry rotation and periodic function testing in a defensive pistol. Shooters seeking a purpose built .357 Sig defensive round will find this DoubleTap load a dependable option.
