I'm going to be a jerk. 1911. It isn't because I dislike it, nor that I don't respect it. It's really quite simple.
1.) For it's size, it's capacity doesn't do it for me. I understand that higher and higher capacities is a new trend; and I am quite young. My thinking has simply been constructed around the idea that more capacity is better, for better or worse.
2.) They're too big for my hand. I've also been constructed around the idea that I like to operate the slide releases, safeties, etc, with one hand. I don't fully know why. I can't even come close to operating these things with one hand on the 1911. This is pure personal preference.
3.) Even if they weren't too big, they feel uncomfortable to me. I don't like the grips. Again, this is probably because I'm used to other designs, but that doesn't make it more comfortable to me.
4.) I'd want a good one, and they're out of my price range. A Springfield Armory, at minimum, with some custom work. I'd
really want a Kimber, so I'd be looking at well over a grand. I will never be wealthy, and can't see myself spending so much on a pistol when XDs, Glocks, M&Ps, and many others with great track records, can be bought for under $500. This is especially true when I value rifles much more highly.
5.) Even compared to something like a Glock 20, the 1911 is far less concealable. I wouldn't want a 4" or 3" 1911 because the grips are basically the same (still too big and too uncomfortable to me), and I like full-sized pistols. 1911s are also much heavier than even the Glock 20.
I don't intend to blaspheme the things, but I will never buy a 1911. They are strong in areas that I don't value highly, weak in areas that I do, don't suit me personally, and are too expensive. I believe them to be great pistols, though! I really do.
