Just wondering because maybe I'm just used to the feel of a quality 1911 but the XD-S seems to have very little tension just off battery. I've heard several reports of FTRB and wonder if a stiffer recoil spring would remedy some or all of them? I know there are several factors that can contribute but if you get a minute, get your XD-S, safety check it (unload it), and pull back slightly on the slide. There will be little or no real pressure holding it into battery which feels unlike every other pistol I've ever owned. Grab any other auto you have laying around and try the same thing. ?????
