I do love a good 1911 and have several. I admit though that it's rare for me to actually CCW one these days.
There were a couple of long periods (lasting a few years) in my life when I daily carried 1911s IWB, usually full sized, all steel versions, but occasionally lightweight Commander sized versions, too, and sometimes even more compact. I always came back to the full sized (or at least Commander sized), all steel, though, because I found that lightweight 1911s too often hit me in the face with spent cases. Never had the problem with all steel 1911s, whether Commander or Government sized. Don't own any lightweights, now.
In total, I must have owned a dozen 1911 handguns, and still own five or six. The only 1911s that I ever had a problem with were three. Two were Kimbers, and one was a Springfield Armory Loaded Model. The two Kimbers, I just sold off. The Springfield was sent back to the factory, and they made it shoot 100% reliable.
Oh, wait, there was also the Ed Brown Kobra Carry, which was unreliable from day one upon receiving it new direct from Ed. I sent it back to Ed, and he fired a few rounds through it, and sent it back to me with no explanation. I called, and he said the only issue with the gun is that I was limpwristing it. Odd, since I had at that time several far less expensive 1911s that never failed to fire.
I kept shooting it (all the while having major reliability issues) till, within just a few hundred more rounds, the extractor hook snapped off. Having lost confidence in Ed, I looked up how to tune a new extractor, bought one from a reputable company, tuned it, installed it, and the gun became 100% reliable, remaining such ever since. That was the late 1990s. It hasn't failed to fire even once since then.
I guess my first attempt at tuning an extractor was a good one. Far better, in fact, than whoever at the Ed Brown shop tuned its original extractor.
