I have. I purchased a Springfield XDm 4.5 10mm last spring, and I’ve been full on with this nice pistol from the day it came home with me. I’ve dry fired until my fingers are sore. I reloaded enough magazines that I developed a strain on the tendon of my left thumb that I’m still wearing a brace for. I’ve cast and reloaded about 750 rounds at this point. This is a quality pistol, and I have utmost faith in it. But as hard as I try, I just can’t shoot it worth a damn. The provided factory test fire target shows that it’ll shoot. I have coworkers that shoot XDm’s just fine. I just can’t shoot this one very accurately. By that, I mean, at ten yards, from a bench, a 2” group is about the best I can do. The two of us just don’t get along. Have you ever had a gun like that?
