I bought my first 1911, a colt wiley clapp commander in 9mm and shot it for the first time today. Put well over 500 rounds through to break it in and test... 124gr HST carry ammo, 115 gr corbons, FMJ, factory mags and wilson mags, not so much as a hiccup. This is actually the first pistol I have ever had that performed this flawlessly on the first day.
This is why i'm surprised... I did a lot of research on the web on 1911s, and really wanted a 9mm for ammo commonality with my other pistols. From what I read over the last few months, I expected all kinds of issue with this thing. Failures to feed, failures to extract, stovepipes, picky with JHP ammo etc. Long story made short I'm a convert to 1911s.
Biggest surprise of the day to me was that I shot some 45 versions that a friend bought and there didn't feel to me like there was all that big of a difference from the 9mm. Although this was immediately after emptying a cylinder on a 500 S&W magnum so my hand was probably still numb.
Have a good veterans day all
