I just got my xd mod 2 tactical in from my local FFL yesterday. I put in a PRP trigger and noticed a problem when checking the reset. If I dry fire, hold the trigger back, rack the slide, and then release the trigger it does not reset. If I put the tiniest bit of pressure on the back of the trigger it will reset and everything will be fine. I took the gun apart and everything appears to be assembled properly. I cleaned it (even though it is a new gun) and saw no change in behavior. I plan to take the pistol to the range tomorrow and see if the same thing happens with real bullets. Does anyone have any ideas what I might have done wrong? Is this just a break-in issue?
