I'm not the best expert on long range rifles, but I have a great amount of experience with pistols. I'm a die hard 1911 lover, even though I don't really see the Paras as true 1911's (though they are fantastic guns), but for CC, a Glock 23 would win my vote hands down. I don't like plastic framed guns and the Glock is about the ugliest gun ever made, but it is also possibly the best tactical gun ever due to its simplicity and reliability. I would much rather go to the range with a 1911, but would never quite feel as secure carrying one that I may actual have to use to engage someone. If conditions were perfect in a shootout, which they never are, yeah sure, I'll take a good 1911. But you just can't beat a Glock, with the simplicity of a revolver, fantastic reliability, good accuracy, etc. You probably know about all the torture tests and all that. As a former cop who carried a Gen 3 Glock 22 and a Glock 27 for years, (and still carry one) I would highly recommend the ugly gun. I'm a big Sig fan as well, but my vote would have to go to the Glock. It's like comparing a Remington PSS with a wood-stocked Weatherby with a light barrel. If you are forced to kill someone with a rifle, I'd go with the black gun that isn't as pretty but you know will put out and put the bullet where it needs to go in extreme conditions.
