Currently I favor my Diamondback pocket 9mm. Just about the same size as an LCP and it is a 9mm which I like for personal protection. Great little gun.
Colt Officer's ACP, done in hardchrome by Dave Lauck of D&L Sports, carried in a Contact! Concealment kydex belt holster, with a D&L Sports kydex dual magazine carrier.
My favorite carry gun is my S&W 686+ in a Lobo iwb holster, but that one gets less carry time than a Glock 30sf. I can shoot the 30 better and faster. Plus 11 rounds are more comforting than 7 rounds.
^^ Looks an awful lot like a Milt Sparks Versa-Max 2, IMHO the best IWB holster ever designed that is still being copied to this day and Sparks 16 week wait time proves it.
