Multiple holsters for multiple handguns is no longer an issue. The Blawkhawk Omnivore multi-fit family of holsters accommodates more than 150 styles of semi-automatic handguns. The active retention mechanism locks onto the proprietary Rail Attachment Device, not the frame of the handgun for the non-light bearing model. Blackhawk's proprietary retention mechanism locks onto the SureFire X300/X300U-A and the Streamlight TLR1/2 for the light bearing models. The instinctive thumb release disengages the locking mechanism from the Rail Attachment Device when drawing the handgun.Specifications and Features:Multi-fit - omnivore holsters fit more than 150 styles of semi-automatic handguns with an accessory rail (Compatible with stream light tlr 1/2 light bearing)Active retention mechanism- ergonomic thumb- Activated retention mechanism delivers instant firearm accessLevel 2 retention - uses two features to hold handgun securely in placeFree-floating design - holster locks onto rail attachment device, doesn't wear firearm's frame and finish3-position adjustable release - height of thumb- Activated retention mechanism adjusts to fit your hand
