This factory original Glock OEM Gen5 Trigger Housing / Ejector Assembly easily replaces a worn out or broken housing. Similar to that of the G43, the Gen5 Trigger Housing / Ejector Assembly eliminates the connector spring and has a slot for the trigger bar to ride in, improving overall stability of the trigger bar. The result is a smoother, more consistent, better-feeling trigger pull. The Glock® Gen5 Trigger Housing / Ejector Assembly has also been upgraded with the trigger return spring moved inside the mechanism housing for better performance. Trigger spring is included with this part.
