I started off IPSC back in 1975 or 6 with a 4" S&W M29, shooting 275 SWC with 21gr. 2400.

I could not get up out of C class, on the edge of B, winning C, but never better.

A friend loaned me his nickle plated 1975-era 1911 - 1st match with that gun put me well into "A", I think 7th or 8th place.
Great gun, even stock.

Now-a-days, it's a race gun sport - form what I've seen, I'm not interested in it. Hell, Cowboy action challenge long range match, where they leg you get set up, before the whistle is about as fast as I move these days.
