Glock Trigger Removal & Installation Instructions

Most people remove the trigger assembly in order to change out the connector or the spring in order to achieve a smoother trigger pull (see trigger work). It's not that hard to do it yourself and can be done in a matter of minutes, especially after you have done it once or twice. The hard part is remembering how it goes back together. That's why I took these pictures, to remind me in case I forget.

REMOVE THE TRIGGER HOUSING PIN

Using a punch, from the left side of the frame, pop out the Glock Trigger Housing Pin. The pin will come out easier if you move the slide stop lever back and forth (or jiggling it) while pushing on the pin.

GLOCK TRIGGER PARTS CLEANING

Clean all removed parts. DO NOT OIL THE PARTS AFTER CLEANING. Oil will just make them a magnet for dirt/contaminants. While all the trigger assembly components are removed why not do a Glock Trigger Job (polishing certain parts to make the trigger smoother)?

GLOCK TRIGGER INSTALLATION

Reconnect the parts and reassemble the trigger assembly by reversing the order of the procedure above. Here are some detail views assembly to help with the positioning and re-installation of the components and their configuration.

  1. Install the trigger assembly. Grab it by the extractor, position it over the frame and carefully push down into the frame. At the same time, guide the trigger into it's corresponding slot. Jiggle it a little if necessary. Make sure the trigger assembly is fully seated into the frame.

  2. Install the locking block. Just position it and push it into the frame.

  3. Install the pins and slide stop lever.

    THE ORDER OF THE FOLLOWING IS IMPORTANT

    - Put the top pin in first (Glock locking block pin).
    - Install the slide stop lever.
