Well, I hate 1911s. Two of the biggest POSs I ever owned were an AMT hardballer, and worse, a Auto Ordinance 1911. The AO would NOT fire anything, but ball and wasn't really 100 percent with that! I'd get a stove pipe occasionally. Sold it at a gun show. I got the hardballer 100 percent, after a trip to a gunsmith, with ball. I also loaded a 200 grain SWC for it, had to load it out to head space on the rifling to get the OAL long enough, though. That gun was real OAL dependent. Want a jam every round, try CCI Lawman 200 grain JHP (old flying ashtrays).
I've never had a jam with my Ruger P90, feeds any and everything I've ever tried in it 100 percent and is awesome accurate. I like having confidence in a firearm.
I own just 4 autos that have proven reliable to me. I really prefer to fire hundreds of rounds in competition (IDPA) if I have the choice before I rely on 'em. I have done that with my Kel Tec P11, my Ruger P85, and my P90. I have a lot more revolvers than I do autos, but my Rugers have proved to be about as reliable. Now, I've never tried any Sigs, know Glocks are reliable, hear great things about CZ, but I'm a revolver guy at heart and I got the Rugers because I like Rugers. They have not disappointed me. But, when it comes down to a social encounter, I know my revolvers aren't gonna jam. Those 1911 POSs still haunt me. I'll never own another, not in my lifetime. I don't like cocked and locked anyway, prefer DA with a decocker if I carry auto or DAO especially in a pocket auto.
If someone forced me to carry a 1911, I could put 2K rounds trouble free through it and still not trust it. LOL
