Ok, so I have decided to take the plunge and get my CWP. Class is tomorrow and am really looking forward to it. I have 90 days before the permit will be in my hands and I want to get geared up. I don't want to waste time and money trying to find a good setup for carrying and could use some advice, mostly on the gun for now, the rest has to wait until I choose my CCW. I have decided to get a 9mm semi-auto pistol with double stack magazine. I am 5-10 or 11 and 230 lbs so concealing a thicker gun is probably not a problem. I like the SA XD series, both the sub-compact and regular 4" are comfortable to shoot. Would the 4" be as easy to conceal as the subcompact with extended mag? With the same number of rounds I'd like the better accuracy of the longer barrel but not at the cost of concealability. What other guns are in these categories (sub compact and compact) with double stack mags? Thanks!
