Hi all. I have a used .45 tactical XD that arrived via a gunbroker purchase in generally good shape. It is has a roll pin poking up out of its hole on the top, rear of the slide. None of my 6 other XD's have this symptom. Can I simply lay the bare slide on my workbench and use a flat steel punch to knock it back in? It looks like about 1/32"+ above the slide.
