Hornady Critical Duty ammunition in .357 SIG (brand part no. 91296) is a defensive load engineered around reliable expansion and stopping power. Hornady manufactures this load to consistent tolerances, so every box performs the same as the last. At the heart of this load is the 135 gr bullet with a flexlock duty design, matched to the .357 SIG platform shooters already run. In our handgun ammunition lineup, this is the Hornady load built for that job.
