Glock 19 in either a MTAC or Blackhawk Serpa depending on what I am wearing or a Diamondback DB9 in a blackhawk pocket holster. With either one I have at least one extra mag with me.
Right now I carry a Glock G19 that is stock, in a RGrizzle Custom holster. It's a IWB/OWB Convertible holster, and it's black leather trimmed out in Sharkskin...
Springfield Government 1911 tends to be the norm when I am not headed to work, sometimes I switch to the Officers model or my Hi-Power, depending on my mood and where I am headed. When I want to carry light, I usually carry my 442, or LCP. Sometimes I have been known to carry a combination of the two.
