I just got this new one delivered an hour ago and already see it's going to be my carry holster. It's sticky on the outside, smooth inside, it has no straps, hooks or anything to keep it in place but it's sticky material. The MD-4, size fits my emp, glocks, all sub compacts. So it fits most all my carry guns. I am wearing nylon gym pants,and it stays up with them. Someone should have thought of this a long time ago, at $30.00 one size fits most, is a terrific little holster. Can be "stuck" anyware on the waist. Very cushioned no hard plastic poking you in the vital areas. Sticky Holsters, so far so good, Goggle them.
