I had a student having accuracy issues during a class so I test fired the weapon to see what was happening. It indeed had a 8-inch drop over 8 yards. The only thing I can say is it was consistent with every round. I suggested he contact Springfield and see what they had to say. In short, he sent it back and they did some testing and indeed there was an issue. Their corrective action was to replace the rear site with a suppressor height site. Has anyone been experiencing site/accuracy issues with their XD 40 and if so is this the corrective action Springfield took to correct the issue?
