I just traded into a pretty nice Military & Police model in the C269xxx serial # range, blued with 4" barrel. It is all matching except the grips and has the "P" proofmark on the barel, cylinder & frame, and is also stamped "U.S. Property" on the backstrap. It also has a lanyard on the butt. I'm curious as to where and to whom these might have been issued. Any thoughts/comments are welcome as this is the first one of these that I have seen.
