Guys: I'll be picking up an XD .45ACP later this month. Right now I'm trying to decide between the normal 4" Service Model and the Compact 4". LINKS: XD Service Model 4" .45ACP XD Compact 4" .45ACP At first I was just going to get the Service Model, but now I see that they offer the "compact" with a shortened grip, using 10 round mags instead of the 13 round mags. The compact can be converted to 13 round mags using grip extensions. Does anyone here have an XD compact? I'm not intending to do CCW...yet...but do you think it would be worthwhile to get the compact w/ extensions? It would be sort of dual-purpose then, I think. The compact doesn't shorten the barrel at all, so the only thing being reduced in size is the grip. Do you think this will have any significant CCW advantage over the Service Model?
