In order of most commonly carried: Kahr CM9, Glock 26, S&W M&P9c, S&W M&P45c, S&W Bodyguard 380, Kimber Ultra Carry II, Glock 17, Taurus 1911, FNX9, FNP9m, and every now and then my Ruger LCP. All good reliable guns in my experience.
Usually carry a 9mm HK P30 with an LEM trigger in a comp-tac MTAC. Replaced my Glock 32 and I absolutely have no regrets. Great shooting pistol. Easy for me to conceal with just about anything I wear during the year.
ParaOrdnance PDA .45 ACP. It's no bigger or heavier than the new "mini" 9s and carries 7 rounds of 45 with the LDA trigger so it can be carried in a pocket ready for action without carrying condition 1. It comes standard with a match barrel and night sights. I took it right out of the box and won a bowling pin match against race guns, and have never had a malfunction. I LOVE this gun!
I carry Glocks most of the time, and rotate through the subcompact lineup of 9X19, .40 S&W, .357 SIG, and .45 ACP. Here's a TruGlo TFO equipped G26 Gen4 in a Comp-Tac MTAC holster:
I carry a single, full-size magazine as a spare, so those would be from 17/22/31/21.
I have yet to get my permit, but when I do, I'll be carrying a Ruger SR40C. I've been wearing it around the house for a couple of weeks now and it's become a part of me. I was pleased to find out I can get in and out of the car without problem and it doesn't dig into my (fat!) waist when sitting.
