Just purchased my first SA product in May and went with the XDM 3.8 Compact in 9mm. So far I have been to the range a few times with it and have been pretty happy. I do notice that it (ok, probably ME!) tends to shoot a little low. Anyone else have this problem? Perhaps there is something I'm doing differently with this model? It doesn't matter if I am using the 19rd or 13rd magazine I still get the same result. I've used some different brands of ammunition but all were 115gr but I don't think that would be the problem. Any suggestions?
