Multiple holsters for multiple handguns is no longer an issue. The BLACKHAWK! OMNIVORE 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 our proprietary Rail Attachment Device, not the frame of the handgun. A thumb release disengages the locking mechanism when drawing the handgun. The OMNIVORE represents the future in retention holster technology, and delivers unparalleled firearm access.SureFire X300U
