Trigger Spring Broke? Keep Shooting!

Posted 07-12-2010 at 23:18 by Butch

A lot of Glock owners (and some ‘would be’ Glock owners), are afraid that the trigger spring on their Glock will break and then the gun won’t work. Not true! You just need to know how to work it!

Some Glockers will go so far as to replace the coil trigger spring with a New York trigger spring to insure that they don’t have a breakage. This does work OK, but it also makes the trigger pull a whole lot heavier, and it’s really not needed.

Most of the time when a coil trigger spring breaks, the shooter doesn’t even know it until a reload is needed because the gun keeps shooting. When the gun is reloaded and the trigger fails to move forward as the slide closes, that’s when the broken spring makes itself known.

The coil spring pulls the trigger bar towards the rear (yeah, the same direction you’re pulling the trigger….it’s helping you pull the trigger), and slightly upward.

When the slide moves back (either manually pulled or when shooting), a shoulder on the slide pushes inward on the connector tab which pushes the connector aside to allow the rear end of the trigger bar to move up where it can be snagged by the firing pin lug as the slide closes.

When your finger is not holding the trigger back as the slide cycles (like when reloading), the upward movement of the trigger bar is provided by the trigger spring. When your trigger finger is holding the trigger to the rear as the slide opens (like when you have just fired a shot), the upward movement of the trigger bar is provided by you/your finger holding the trigger back.

Now, when you reload and the trigger fails to move forward as the slide closes, and you REALLY want to fire the gun, just pull and *hold* the trigger to the rear while you rack the slide. Yes, you’ll lose the round that was already chambered, but now the gun will work normally until you need to reload it again!

Can I guarantee that it will always work? No, but I’ve never seen it not work. You can try this by removing the trigger spring from the gun and shooting it. You can also dry fire it this way as long as you remember to hold the trigger back while you rack the slide between ‘shots’.

One more reason to be less concerned about coil type trigger spring breakage; the new Gen4 trigger bars have a change on them where the coil spring hooks onto them. That part of the trigger bar has been altered so the hook of the spring rides against a more contoured piece of metal. This way all the pressure put on the spring’s hook isn’t in just one spot like it is on the original trigger bars. It appears to be a good way to minimize spring breakage. I can easily say that Glock would probably be making this change to all of their trigger bars, the only downside might be that one would need to be sure to install it correctly.

    This was demonstrated to us in the Glock Armorer Course I took in June. The instructor had us REMOVE the spring to show us how to run the gun in the event of a break. Its still incredible to me that a gun will still run with a major part removed (or broken).

    After the first time you manually cycle the slide (after breakage), the firing of a round will continue to cycle the slide thereafter.

    Thanks for the info & pics! I was just reading a post on The Firing Line where concerns were that the trigger spring made the Glock unreliable. Never had a problem with mine, but next time I'll have a good answer.

    If the Gen 4 trigger bar is the answer, can the Gen 4 trigger bar go in my Gen 3 pistol?
