Though it's not on your list, may I suggest you take a look at the Ruger P345? It has a very thin profile which makes it great for CC. It's also very reliable, I've put 5K+ rounds though mine without a single failure to feed or eject. I also give it high marks as far as accuracy goes -- I am definitely the weak link in that chain. It's also priced right. You can find the blued model for around $425 or the stainless for about $450. Here's a link if you'd like to take a look.
