Speer Lawman 357 SIG caliber 125gr TMJ ammunition. Info from Speer web page....Training with ammunition that gives you the feel and performance of premium ammo gives you the edge you need when duty calls. However, using premium hollow point ammunition for target practice and training is not cost-effective. That's where SPEER® Lawman® comes in. It delivers all the performance of premium ammo for a fraction of the cost. Lawman uses high-value brass cases, CCI® primers and SPEER TMJ® or conventional full metal jacketed bullets. The end result: tight groups and consistent pressure and velocity, every time you squeeze the trigger. If you're looking for high-quality ammunition in traditional reloadable brass, Lawman is your ammunition.
