I had a Hi Power built up by C&S back in the late 80's or early 90's. Recently it cracked the locking lug in the slide and I sent it back for repair. When I was talking to them about sending it back they asked how many rounds through it? When I told them about 20K they said they liked to see high round count guns to see how they held up.
Mine is a safe queen now. I ran it in IDPA for a year. Got my Master classification shooting that gun. Scott Warren shot one for the first few years in IDPA.
