I took my S & W K-22 Masterpiece in for a cleaning. It is 30+ years old with very minimal holster wear and came out with a very deep 1/2 inch scratch. Maybe "Matt" knows what he's doing but his apprentice(s) sure DON'T!! I'll never go back there again, since he didn't even say he/they were sorry, only that "he doesn't remember seeing the scratch"!!! I will say he didn't charge me for the cleaning, but that hardly pays for the value loss the weapon has sustained. Find someone who treats your collectables with respect and care.
