My Kimber Custom II (bought used) has been utterly, boringly reliable, just as reliable as the Glock 21 I had previously, I know Kimbers generally don't have the best reputation here on THR, especially the Custom II series, but all I can say is that *MY* KCII, when used with Wilson or CMC mags has been completely, boringly reliable, feeds anything and everything, ball, HP, LSWC, it has, so far, never jammed, stovepiped, FTE, or had any other stoppages that were not caused directly by me (not slapping the mag in all the way, for example)
I've put well over 2,000 rounds through it, a mix of WWB ball, Speer Gold Dot defensive ammo, and my handloads, my Kimber has been incredibly, boringly reliable, and it's essentially bone stock, aside from a curved mainspring housing, and to top it off, it's still the most accurate pistol I have shot
It took me a while to arrive at my choice of a 1911 as my main pistol, and I can't see going back
Previous guns I have owned and gotten rid of to end up at the 1911;
Taurus PT-99AF; initially okay, but began stovepiping after around 500 rounds, traded off
Glock 21 (standard, non-SF); a decent gun, boringly reliable, but the grip was a hair too wide for my hands (wide palms, stubby fingers), so it was traded off
CZ-75B; I *LOVED* that gun, most accurate 9mm I have shot, and still kick myself for selling it, but money was tight, I had recently purchased the KCII, and since I reload for .45, shooting .45 in the KCII was actually *cheaper* than shooting factory WWB 9mm (I couldn't afford reloading gear for the 9mm or I would have reloaded that as well), if I did reload for 9mm, I would have to have stocked small pistol primers and bullets for that caliber too, and that was in the depths of the ammo/component shortage of '08-'09, I had plenty of components for .45 ACP though....
At some point, I *will* own another CZ-75, as it's just a brilliant gun, ideally, I'd get a CZ-75SA, to keep the manual of arms consistent between the two guns
So, my experience with the 1911 has been overwhelmengly positive, as reliable as the Glock, plus, I can shoot lead and reloads without having to drop in a conventionally rifled barrel, the 1911 fits my hand better and points more naturally than the Glock as well
Now bear in mind here that I'm *NOT* bashing Glock, they are excellent guns, reliable, sturdy, accurate, and with a nice high capacity, they just don't fit my hand, that is all, if the Glock grip fit my hand, I'd have no problem owning one
That said, for my purposes, the 1911 fits me well, I shoot it well, and my particular 1911 just works, I'd have no problem trusting my life to it
