When absolute concealment is needed (in New Orleans, where my CCW permit is not accepted in La), I "might" carry my .22 LR Beretta in my Aker's pocket holster. Of course, that would be illegal, so I only "think' about doing that.
For my CCW, now a .45 Kimber/4" barrel:
I have been carrying my Kimber in either a M.S. Summer Special or a KC gun leather IWB holster that basically copies the look of the M.S. Heritage.
Am currently waiting for delivery on a Milt Sparks Executives Companion for the Kimber. (10-12 weeks is a LLOOONNNNGG time) haha
For belt carry not concealed or when concealed under a winter coat, etc.... in the past I have always used a Yaqui slide.
