The Gen 4 G19 upper parts kit takes the same twelve piece approach as the Gen 1-3 set but upgrades where it counts: nitrided firing pin safety and depressor plunger, and a Zaffiri stainless steel recoil spring assembly at OEM spring weight in place of the polymer guide rod. Extractor, bearing, channel liner and cover plate all included.
It suits a bare compact slide such as this FDE G19 slide without barrel, and the wider range is under Glock parts.
