I have an XD40 with 4 inch barrel. Bought it new from a dealer and even got the XD gear bonus stuff with it. Holster, speed loader, 4 mags etc. I'm happy with it and I love the way it fits my hand.
My only complaint is if I don't hold it extremely tight it will jam. If I lock my arms and hold it in a death grip its fine and reliable. Any one else have this problem? Will it go away as the gun gets broken in?
