I have never been able to carry a revolver, since I only have a 6" L-Frame and a 4" N-Frame and don't have particularly good holsters for CC for them, and I have actually never fired a 1911. I blame that on not having any friends who have taken the plunge and bought a gun of their own, and that my family is extremely anti-gun. Anti-weapon really.
Anyway my first gun was an HK USP .40 fullsize, and I find that it conceals pretty well. If you are moving to or living in Texas, I would check out something like the Glock 27, I bought one a year ago when I got my carry permit in anticipation of summertime carry. That gun is extremely compact, the barrel is long enough to let JHP loads work like they were designed to, it is short enough that it doesn't irritate me while sitting, the grip takes some gettingn used to because it really does work best without a mag extension, just letting the pinky curl underneath it, but it still holds 9+1 rounds or 10+1 if you get the 26 instead. Also, it is accurate, just as accurate as my other pistols. And it is pretty light as well.
I feel that it is the smallest and tightest package for CC that doesn't give up anything major. Some guns may be more accurate, but it is definitely good to go as far as service/defense accuracy goes, some pistols do hold more rounds, but not in the same size, and even out of other subcompacts it is one of if not the shortest from mag basepad to the top of the slide. I'm not counting pocket .380s and .32s in that comparison, only subcompact versions of service pistols.
I also carry a Glock 23 (the 27 won me over in a big way), a CZ 75D PCR (fantastic pistol, totally reliable and it can take an extremely high-quality .22 conversion kit), and also an FNP-9M which is a great gun.
