The holster itself is not bad per se, but it's assembly is terrible. in order to fit my FNX-45 I had to remove two inserts, but as the inserts were working as washers, the belt support and the reversible side cap now wobble. nothing that can't be fixed with a couple of washers, but still bothersome. The screw/nut system holding the holster together is terrible. If you are using a full size pistol with a flashlight (which is probably the case, otherwise you'd be picking another holster) you're gonna have these issues. The retention system uses these weird nut/screws and it's very loose as well.
very good fits my m9 1911 and browning hi power with no adjustment
