After discovering my concealed holster doesn't lend itself well to re-holstering my gun, I've been looking into molded plastic holsters. Looking closer at their designs, I'm thinking I'd like to try making my own. I have considerable experience with thermoforming and basic construction. The planned holster would be an IWB (small of back) style for my SIG Pro 2022. I would use .093" thick ABS and use a slightly wider belt button loop orientation for more stability than a standard single J or S hook. Question: should i attempt to line the inside of the holster with nylon or other fabric to decrease the amount of wear on the finish?
