I bought this in 1980. NIB, came with 2 (50rnd) boxes of Federal 185gr JHP. $369 plus tax.
All the rest of my .45ACP semi auto pistols are 1911A1 pattern guns.
Double stack firepower is of no concern to me. And, while it took me a few years, I am finally OK with the heel type mag release. It is a slight disadvantage in timed combat style games, but then, the gun wasn't made for playing games.
Over the years I have come to realize that, for me, the highest practical firepower and fastest mag changes are rather irrelevant. My gun is bone stock, never had any work done on it. Works flawlessly, and feeds everything with a bullet (I never tried feeding an empty case, why would you?)
Handles loads that are too hot for a stock 1911A1, and also cycles with loads too light to work in those same 1911s. While I never did a formal round count, the gun has had between 8-10,000 rnds through it over the 35 years I've been shooting it.
I think that is plenty good enough, and when I see this or that gun did a 30 or 50k test run, all I do is yawn. That's wonderful, but its not a selling point to me. I have never taken an interest in any of the other guns in the poll, so will not comment on them, other than the fact that since I had my BDA (Sig P220), I never had a need for another DA/SA .45ACP.
Get what you like best, but you won't be going wrong with a P220.
