SIE,
My everyday carry is a 3953 in a Blade-tech IWB. I shoot 3-gun with a Blade-tech stingray (CZ75). Both are adjustable for belt width and cant, and both are IDPA approved.
I don't think you're going to find a holster that doesn't wear the finish to some extent. When you choose a shooter or a carry piece, wear is going to be inevitable. You're going to ding the grips, get some muzzle wear on a revolver, etc..
The edges of the slide are "shiny" on my 3953, but the fact is I like to shoot my guns, and a little wear doesn't break my heart.
Hope this helps.
