Consistent Feeding & Function Carefully profiled ogive and precise component assembly support smooth chambering in most .40 S&W duty pistols and PCCs. Balanced Recoil & Control The 125-grain load offers a manageable impulse for fast follow-up shots and tighter accountability—ideal for defensive standards and qualifications. Case-Quantity Value Convenient 10-box case (200 rounds) lets you test, train, and carry the same load—improving real-world confidence.
