I have 7 different 1911s, including one early P14-45. IMHO, it is a POS.
I have had quite a few failures to feed in my P14, typically near the end of a magazine. Yes, the magazines are original PO magazines, that I got straight from PO. Yes, I've tried replacing the mag followers and springs.
In addition, after putting several thousand rounds through the gun, the hammer started following the slide down. As a result, my gunsmith had to replace the hammer, sear, and disconnector.
Now the slide stop notch is getting misshapen, so the slide will have to be repaired or replaced.
Eventually I will have it built into an IPSC gun. I'll keep the magazines and frame. Everything else will go in the trash.
In short, my P14 has proved to be unreliable, poorly finished, and not durable.
I'd buy another Kimber. I won't buy another PO. YMMV.
