You are buying a "Uncle Mike's Sidekick Handgun Holster". Size is a 20 according to the tag. (Fits most standard handguns). This is "used" but was hardly ever actually used, maybe 6-8 total times. It is in excellent condition, everything works, and there is absolutely nothing wrong with it. These run around $100 & that's without the belt attachment that this one has on it. It can be taken off if you don't like it.
