I didn't like the shorter grip either. I haven't bought an SC mag yet because of the pinky.Thanks for the information! When I convert my compact/carry to subcompact mode I don't like the shorter grip so I've been using a 15rd mag with a grip extension. It makes it basically the same size as the compact, but the small grip and no rail makes it easier to conceal. I'd prefer a pinky extension over a 15 rd mag. (I think, heh).
I bought these Pachmayr grip extenders for my P320SC that fit and work great for me.Anyone get a pinky extension that fits and works?
