The most accurate handgun I've ever fired is my Norinco 1911, made by real Communists in China. It digests anything I choose to put in the magazine, from hardball to the flat Keith bullets I use for reloads.
It's very nearly "see it, put a hole there", pointing it like a finger. It's like magic. I'm only a barely passable marksman under normal circumstances, but the Norinco makes me look like I know what I'm doing.
I have, and have had, other handguns, some of them very fine, with no mechanical problems, that I couldn't hit a phone booth with if I was standing inside. Certainly my problem, not the guns'.
I vowed to keep the Norinco forever, and never to change a thing. Unfortunately it suffered from the dreaded "barrel lug setback" that afflicted some percentage of Norincos, and I had to replace the barrel. I haven't had it out to the range since the transplant. I'm not really expecting any change, though.
