You'd be surprised what leather holsters can do over a long period of time. Since he got in in 1980, it's likely leather was the holster used to carry it in.Not from any holster I've heard of to get into all of those contours and crevices that completely. That gun looks stainless and the only wear I can see is at the front of the slide at the Interams stamp.
It's not just the drawing of the pistol, but the movement during actual wear. Most police leave their guns in the holster and just take the holster/belt off at the end of the day. But leather eventually stretches and that causes wear as the gun shifts around in the holsters. That's why I like Cordura or Kydex. My experience there is much less wear using those holsters. Sure glad that isn't a blued steel gun. Rust and pitting would have done a real number on bare steel.I see that Photohause has said that it's stainless....D'oh! But still, that is a lot fo draws to cause that kind of wear at the front of the slide. A well used and obviously valued gun. Congrats!
Bingo. Somebody give Zonadrill a cigar.I see this is marked as a west german gun. I thought the west german guns were not made in stainless. Could this have been refinished?
