I was looking this web over and noticed--Gorknoids (on 3-14)--had the same problem I had today with my brand new 9mm XD. I encountered very light striker hits on the primers....so light that the gun did not fire. I cleaned the gun prior to shooting it---just like the gun store owner said . New ammo was used and several fellas at the range suggested that I use some of their ammo...they thought that my Federal ammo might have been bad. NO, all ammo responded with the same end result----no bang ! I have been told to switch the striker spring to a Wolf brand. Is this usual for a brand new gun ? The gun store owner told me that the XD was "bullet proof" ,I didn't think he was referring to the gun "not shooting" ! Does anyone have any suggestions ? I can't tear the gun down to fix it,I don't know how,and wonder if I bought a "problem child". I intend to take a CCW class and carry this thing. Am I starting off on the wrong foot altogether ?
