How does the finish wear on the MKIII compared to a blued Browning Hi-Power? I am specifically think of holster wear.
The finish holds up great. With a quality holster it will last a long time.
Finish wears in exactly the same areas a blued pistol would wear. My Mk. 3 that I've carried for over 2 years now is showing holster wear on the front top corners of both sides of the slide. Just under the front of the dovetail. It took over a year to wear that much. So I believe a shiney blued pistol would wear a a little sooner.
