CZ's only subcompact, the 3" barrel RAMI, is by far the world's best IWB Concealed Carry pistol, IMHO. Its 15 round capacity with the legendary CZ ergonomics of its supplied extended magazine is 2nd to none in its class, because it stands alone in its class with its 7075 T6 aluminum frame, and the full-fingered forward-hooking grip will spoil you for anything else once felt. Its competitors are pudgy-barrelled, polymer framed, and tall bore center, thus nowhere near as soft shooting. I've found 12:00 IWB via Crossbreed's SuperTuck modified to sink all but the hammer and the butt of the grip below the belt enables total concealment with tucked shirt, and seated/bent over comfort. The BD model avoids the possibility of forgetting the safety under stress, while providing a land between the slide release and the decocker lever for one's strong thumb, safe from the whizzing serrations of competitor's external rail designs. As CZ's lightest offering, it can be carried all day without duress. It's worth saving up for and waiting in line for, if need be.
