CZ75, I own it, and here's why: it feels, and points, like it was made from a mould of my hand. The factory trigger is very good, and is tunable to fantastic. It shoots where I look. It's reliable as anything I've ever seen. It's made of all steel, eats just about anything and asks for more, recoil feels barely more noticeable than a .22, and it's way more accurate than any GLOCK I've fired.
Beretta 92, I carried one overseas, and here's why: It's extremely comfortable to shoot (if your hands are big enough), it has a very short trigger reset, it's one of the most tested guns of all time, and they are quite accurate and reliable.
SIG P228 or P229, I carried one overseas, and here's why: It's easier to conceal than a Beretta, the design is much more elegant and simple than the Beretta, it's very, very accurate, the triggers are very, very good right out of the box, and they are very reliable.
S&W 3913, I wish could scrounge up the cash to buy one, and here's why: slender, good-feeling gun, beautiful, and one of the most concealable of the ones I'm mentioning.
HKP7, I wish I could scrounge up the cash to buy one, and here's why: everything I said about the S&W, and it's freaking cool, with an awesome trigger, low bore axis, and incredible accuracy reputation.
