This is the trigger that comes in our ultimate line of trigger kits. It is designed to work in conjunction with our striker safety lever. We do not recommended that you buy this part as a stand alone item. The only reason that it is listed this way is so that people can upgrade from the old style over travel stop on line. This part is over sized and will need to be fit. This trigger is a Springfield Armory OEM part available on production XD and XDM pistols from the factory (see APPENDIX D4 — 21.6 Production Division rules).
