Recently purchased an XD for my birthday. Nice gun! Problem is, it shoot low and to the right (shot from bench rest). I took it to the shop where I bought it and the gunsmith tried moving the rear sight using a sight pusher. Darned thing would not move, in fact, he broke the rod on the pusher. I called Springfield and was told that they use a punch and hammer. I tried that with no success. I don't want to beat the crap out of it. Anyone have a similar experience or suggestions. Thanks!
