Multiple holsters for multiple handguns is no longer an issue. The Blackhawk(R) Omnivore(TM) is a multi-fit holster that accommodates more than 150 styles of semi-automatic handguns with an accessory rail. The active retention mechanism locks onto Blackhawk's proprietary Rail Attachment Device, not the frame of the handgun. A thumb release disengages the locking mechanism when drawing the handgun.Features :Level 2 Retention - Uses two features to hold handgun securely in placeFree-Floating Design - Holster locks onto Rail attachment Devise, doesn't wear firearm' frame and finish3-Position Adjustable Release - Height of thumb-activated retention mechanism adjusts to fit your handLeft handFor Semi-Automatic Handguns with Streamlight TLR 1 & 2
