Appendix D4 21.6 Sights, firing pins, f iring pin retainers, pins, extractors, magazine releases, slide stops, thumb safeties, triggers, hammers, bushings, andejectors MAY be replaced with OFM or aftermarket parts. So does this mean we can use any aftermarket trigger we want on a production gun? I think this thread needs some significant updating on the first post.
