As I said before, I have a Para, Springfield and a Kimber, all are 1911s. Of the three the:
Para is is most temperamental and it needs to go back. The fix might cost me some $ as I got it as a problem child so no surprises on that one.
Springfield is the range queen, my daughter's love it. No issues, except I never get to shoot it.
Kimber (Ultra Cary II) is my daily carry. No issues. Took the Apex class and shot about 350 rounds. No failures... Well one time I didn't seat the mag on a tactical reload, that's on me. I was able to fire the required shot after reload as it doesn't have a mag safety (I won't have one). Just fire, seat the mag, slingshot.
I hear problems about 9mm 1911's but really don't experience them.
