Hello from NC. I joined the forum a couple of weeks ago when I bought the XDS .45 with the 3.3. inch barrel. This past Saturday, I picked up the XD .45 Service Model with the 4 inch barrel and thumb safety. I got a chance to fire both weapons this weekend and they both shot very well. I was expecting a lot of recoil with the XDS but it was very manageable. The service model was a blast to fire as well. Shot some real tight groups. I have medium sized hands and I was able to fire the Service Model very comfortably. Can't wait for the next time I go to the range.
