I had an XD-40 subcompact, now I have an XDm-40 3.8". I find the XD series to have less felt recoil than their main 2 competitors, and ergonomically they are fantastic. Pros are the way it feels in the hand and the way it shoots. Pro to me and con to others is the grip safety; I find it to be an endearing feature and other think it is a bad idea. Con, if you are planning to CC, is it is thicker than a lot of other choices.
What I tell everyone else is, give the XD a try! It may be right for you, but if it isn't it's a MACHINE, get something that works. Another plus in your case is you have found a DEAL; a great bargain pulls a lot of weight in an otherwise equal decision.
