While I own a couple of double stack 9mm pistols, my hands are small enough that I just really don't have a great passion for any of the more modern, double stack pistols. A 1911 fits my hand very well, however - it's a proven design that works well, .45acp is a great calibre, IMO, and 7 or 8 rounds is sufficient as far as I'm concerned (given most of my other hand guns are revolvers anyway). I also like a hand gun with some serious weight, and have not taken to any of the light weight pistols I've tried or owned.
Even my "little" .380 is an all stainless frame and slide P232 (~24oz).
My next 1911 will be an series 70 colt gov't - not a reproduction, I'm holding out for a good specimen of the real deal (just missed out on a mint condition one last spring).
