I typically carry my Para Ordinance single stack 3" 1911 (called the "slim hawg", single stack version of their warthog). LOVE this gun as an incredibly comfortable ccw 45.
If not carrying that, carrying my beloved Springfield XD 45, 4" barrel in a Blackhawk SERPA II holster.
I am in the process of getting my LTCH. When I get it I will be carrying a Taurus 738 TCP. I also have a Ruger P94 that I could carry but it is awful big.
Glock is the only thing I will carry. I do have a few "pocket pistols" that I will carry if I am not dressed to conceal my Glock, but as far as every day normal carry, Glock for me. Particularly 27 or 30.
