How a Glock Trigger Works - Factory Cut-away

Duration: 4:14

This video details the internal mechanics of a Glock 19 trigger using a factory cutaway. It explains how the trigger bar, connector, firing pin, and firing pin block interact to safely discharge the firearm. The explanation highlights how the trigger safety ('dingus') functions and how the trigger bar's engagement with the connector allows the firing pin to be released.

Quick Summary

The Glock 19 trigger mechanism utilizes a trigger bar that directly engages the firing pin's sear. As the trigger is pulled, the connector pushes the trigger bar down, releasing the firing pin. A firing pin block, lifted by the trigger bar, ensures the firing pin only moves forward when safe.

Frequently Asked Questions

How does the trigger safety ('dingus') on a Glock work?

The 'trigger dingus' is a lever hinged on the trigger. When forward, it physically blocks the trigger from moving backward. As you pull the trigger, this lever pivots out of the way, allowing the trigger to complete its travel and initiate the firing sequence.

What is the role of the trigger bar in a Glock's firing mechanism?

The trigger bar is a stamped steel component that directly connects the trigger to the firing pin. It presses on the firing pin's sear surface, holding it back until the connector pushes the trigger bar down, releasing the firing pin.

How does the connector influence the Glock trigger pull?

The connector has a sloped surface that interacts with the trigger bar. As the trigger is pulled fully, this slope forces the trigger bar downward, causing it to slip off the firing pin's sear and allowing the firing pin to move forward.

What is the function of the firing pin block in a Glock?

The firing pin block is a safety mechanism. A raised part of the trigger bar pushes this block upward as the trigger is pulled. The firing pin cannot move forward to strike the primer unless this block is out of its path.
