I dont know about the firing pin imprint but I picked up an XD45 today and there is a promotion going on until November 30. Buy a new XD or XDM and get 3 mags and a double mag holder free. You will need to scan your receipt in jpeg to do the deed on line. Anyone that bought an XD recently need to go to the Springfield website.
