Glock Factory Trigger Housing w/ Ejector 20/21/29/30/40/41 SF/Gen4

Glock Factory Trigger Housing w/ Ejector 20/21/29/30/40/41 SF/Gen4 is a genuine Glock OEM trigger mechanism housing that anchors the fire-control components inside your pistol's frame and comes with the 8196-2 ejector already in place. A factory part and not an aftermarket copy, this trigger housing drops into the platform exactly as designed, restoring correct ejection and fire-control geometry. This makes sure that spent cases clear cleanly and the trigger resets in the way the pistol was built for. For anyone rebuilding or maintaining a large-frame Glock, an OEM fit is the standout benefit that creates no guesswork, no fitting, and no compatibility surprises.

This is a fitment-specific component, so matching it to the right pistol is critical. The GL5406 housing fits 10mm and 45 ACP Gen3 SF and Gen4 Glocks, covering the G20SF, G21SF, G29SF, and G30SF, as well as all Gen4 10mm or 45 ACP pistols. It corresponds to part number 22 on the Glock schematic and carries the correct 8196-2 ejector for these calibers, which is what separates it from the housings used on 9mm, .40, and standard-frame models. If you're servicing a subcompact G29SF, a full-size G20SF or G21SF, a compact G30SF, or a Gen4 10mm or 45 ACP build, this is the housing and ejector assembly Glock specified for those guns.

The 8196-2 ejector installed in this housing is the detail that makes ejection reliable on 10mm and 45 ACP frames. Using the factory pairing keeps your slide-cycling and case-clearance behavior true to spec. Sold as a single unit in black to match Glock's factory finish, this trigger housing is a clean, direct replacement for a worn, damaged, or missing housing, and is also a good spare to keep on the bench for a large-frame build.
