IDPA = pro compact use
IDPA is a game trying to be reality. That being the case, it is often mentioned that the use of a carry gun for competing is useful. Ideally, if you're starting out, I'd recommend that you shoot with whatever you're more comfortable with (in terms of carrying and accuracy); Be it a compact or full size model.
I've seen many a competitor carry a compact. During the first match I ever attended a Safety Officer in my squad was shooting a Glock 26.
As for the holster, as long as it meets IDPA requirements and it is comfortable, get it. That may mean different things to different people, though and in all reality, you'll probably need to try on a few holsters before you find the 'one'. I personally run a G19 with a blackhawk! nylon IWB holster.
