The BlackHawk Serpa model holster is their flagship holster design, used by SOCCOM, US border patrol, and the US marines, as well as civilians and law enforcement personnel all over the world. The BlackHawk Serpa Auto Lock release is activated intuitively, with your index finger positioned along the side of the holster so it ends up exactly where it should be once you have drawn the gun - along the top of your handgun. Serpa holsters also feature the Blackhawk passive retention detent adjustment screw, so each Serpa model comes at Retention Level II to begin with. Some versions add a thumb-activated Pivot Guard for Level III security. Choose from a variety of mounting options for your BlackHawk Serpa holster: belt loop, paddle assembly, shoulder harness, thigh rig, or MOLLE mount. The 3-screw mounting system makes each BlackHawk Serpa Holster adjustable for cant. Consider adding a quick disconnect kit so you can quickly switch between different mounting options. Remember to practice to build muscle memory with any holster, especially retention holsters.
