Now that's a good start for your first post!
Good looking holster and extension grip. I use a Don Hume holster that is very similar to yours (open top, leather, belt), but with a Service XD40. I never could stand IWB. Paddle holsters are too loose for CCW. I want the butt of the grip against my side, and a paddle holster doesn't do it (at least the four or five that I've tried).
Someday I may get a subcompact. I am considering several - XD, Sig, Walther, or a 1911 compact. So many choices!
