Grizzly Ammo ammunition in .357 SIG (brand part no. GC357S3) is a hunting-handgun load built for deep penetration on tough game. Grizzly Ammo backs this load with the quality control shooters expect from a name they already trust. At the heart of this load is the 125 gr bullet with a full metal jacket flat point design, matched to the .357 SIG platform shooters already run. In our handgun ammunition lineup, this is the Grizzly Ammo load built for that job.
