This unique holster design allows you to forget old-fashioned thumb breaks that slow your draw and complicate reholstering. The patented SERPA Technology lock engages the trigger guard as you holster the pistol and won't let go until you release it. The release is made using your normal drawing motion, with the trigger finger beside the holster body. SERPA Technology Features: Full firing grip for draw and immediate retention upon reholstering. No thumb break or awkward middle finger release to slow down your draw. Speed cut allows faster draw and easy reholsterIng.
