Does the Glock work? I suppose so (outside of "KB malfunctions"). Personally, though, I think it's ugly, square, it has a goofy trigger, and there's that stupid notch on the bottom of the triggerguard that chews up the knuckle on my middle finger. That one alone does it for me. No thank you. If it suits you, great. If they suited me, I'd have one. But they don't.
I'm always bemused by the claims that "the 1911 isn't reliable!", and wonder where the he// that comes from? I can only imagine that it may come from the fact that today, everybody and their brother makes a 1911.... and they don't all do a good job of it. And YES, they often do need work when brand new. It is irritating, and shouldn't be that way, I agree. But these are manufacturing problems, not design problems.
