What's a Sticky Holster? Since our inception, we have developed these holsters into a modular system, where you can use it IWB, in the pocket, on your ankle using our ankle rig, and for police officers, on their tactical/armored vest, etc. They don't come with clips or loops to secure it in place, as the outer "sticky" skin adheres to your waistband, undergarments, and/or your skin. The outside skin is a super non-slip material that, with a little pressure, adheres to just about anything. In the pocket, it works like any other pocket holster. However, when you pull the gun, the outer layer grabs the inside of your pocket. Our modular products use the same "Sticky" material against itself to hold the holster and gun in place. In addition, with use and body heat, your Sticky Holster will conform to your particular gun, making a custom fit.
