My XDm shoots about 3" to the left. I am curious as to what the best option for fixing that may be. Do I drift the sight over to compensate? I have read here that others have sent theirs back to Springfield to have the adjusted to shot POA. Do they just move the sights or do they replace them with some sort of offset sight? Just curious. I have tried drifting them over already, but I haven't been able to get them to budge. I have read they are pretty tight and require a bit of extra convincing to move.
