It's a matter of Conveneince..I carry my G-23 in a Fobus back and forth to work, and until recently uses a Pancake for Off-duty since the Fobus sticks out and priints Badly in most cases (Mine is a Roto, which is worse, it's wider because of the design) the standard paddles actually arent that bad. Just switched to a non-roto since i put a light on the Glock, and it Does ride a lot closer, and conceals better..That said i've seen WAY too many fobus rivets loosen up..not a big deal, but something to keep an eye on.
