Glock 20/21/29/30/40/41 SF/Gen4 Trigger Housing w/ Ejector Features The Glock Trigger Housing with Ejector anchors the fire-control components inside the frame and because it is a genuine factory part rather than an aftermarket copy it drops into the platform exactly as designed with no fitting or guesswork required. The included 8196-2 ejector comes pre-installed in the housing ensuring spent cases clear cleanly while the trigger resets correctly for the next shot. This housing corresponds to part number 22 on the Glock schematic and carries the ejector specification correct for 10mm and .45 ACP frames which is what separates it from housings used on 9mm .40 or standard-frame models. For anyone rebuilding or maintaining a large-frame Glock an OEM fit is the standout benefit eliminating the compatibility surprises that come with generic replacement parts. This housing and ejector assembly fits the G20SF G21SF G29SF and G30SF along with every Gen4 10mm or .45 ACP pistol making it the correct part specified by Glock for those exact models. Using the factory pairing of housing and ejector keeps slide-cycling and case-clearance behavior true to spec which matters most on pistols carried for duty or self-defense. Sold as a single unit finished in black to match Glock s factory finish this housing is a clean direct replacement for a worn damaged or missing part. Available for sale at GrabAGun this is the housing and ejector Glock owners and armorers need for a dependable fire-control rebuild on their large-frame 10mm or .45 ACP pistol.
