The Stern Defense H2S Hybrid 2 Stage Drop-In Trigger Group is designed specifically for pistol caliber carbines and defensive shooters. This hybrid trigger combines the durability of Mil-Spec triggers with the responsiveness of competition-grade triggers. As a direct drop-in replacement, it has been rigorously tested with over 250,000 rounds, proving its reliability. The trigger offers a smooth 2 lb. first stage, followed by a firm 4 lb. second stage with a crisp break and a predictable reset. Equipped with a duty spring, it prevents accidental bump fires and reset failures, common in PCC triggers. For an even lighter, more defined break, switch to the 3 lb. green spring following the easy installation instructions.
