I carry according to my need and dress, but currently I carry the most a .357mag, Chiappa Rhino 200DS.
If I'm just stepping out and in my shorts and a light shirt I slipping into my wasteband a 9mm, Kahr TP-9 (first model).
When I know that I going into a bad area due to my job either my .45acp Springfield 1911-A1 (Govt), ATI FX45 GI1911 (Cmdr), or a custom 9mm, CZ 75 D PCR, all depending on how I fee and of course dress.
The Mini Draco pistol in the photo may or may not still be in my collection by the end of the week (Never to be imported again Mini Draco LNIB : Semi Auto Pistols at GunBroker.com) but after seeing one go for $1700 + (Draco Mini AKM / AK-47 - 2 x 30 round mags 7.5" : Semi Auto Pistols at GunBroker.com) just the other day I just had to see if there was another person out there willing to give me the same. But it doesn't matter, if it's still mine at the end of the week, then eventually at some point it'll be turned into a SBR.
The .38spl +P S&W 642 is something that I pickup for the wifey to have around the house when I'm on the road.
