I dont worry about what a holster is gonna do to a guns finish. If a gun is going to be carried, its gonna get wear on it, plain and simple.
On my hip...XD Compact .45
This ... my Colt has some wear on the bluing from carrying. GC is always trying to get me to get it refinished. I kinda like the "experienced" look, myself ... LOL **
** Note to GED: BE NICE!!!
Oh my hip now: nada
When we leave the house in a bit: my trusty Colt will be in my purse. GC will have his G32.
