Hazard 4 Stick-up Modular Velcro Universal Pistol/Gear Holster by Hazard 4, Coyote

This velcro-hook-backed holster is compatible with many Hazard 4(R) packs/bags and will also work with your existing loop-velcro-faced gear to secure your pistols and other gear where it is most convenient to reach. It is also the only holster in its class with an adjustable thumb-break-style retainer. It fits anything from a power charger for a laptop to just about any modern semi-auto pistol. It also holds AR-15/M4/M16 magazines. The fact that it has a removable retainer makes it much safer to carry pistols inside your bag since the gun can't come out of the holster inadvertently or be bumped out. This could cause an unsafe condition where the trigger is free to be pressed by another object in the bag or an external force. If the retainer is not something you require, it can be removed in seconds. The holster can be set up for left or right hand release and the retainer can go over the back of the pistol's striker/hammer, or below the slide above the grip. When used upside-down, the retainer holds objects such as power adapters from dropping out. A very versatile solution to a number of carry-situations.
