Glock 23 gen 3 Spring Failure

2136 Views 12 Replies 6 Participants Last post by  biohazard2m
My father's Gen 3 slide spring failed on him at the range. During a shooting session, his slide simply slid forward and fell off of the gun. He is retired LEO who has had a Glock for years and said he'd never seen that before in such a reliable brand. He ordered a new spring, just thought I would share that with you all.

Any idea of how many rounds that spring had on it? I bet it was a lot.
Not off the top of my head, but you're probably right. It was his go-to for many years. His favorite has since been a 10mm.
Did it break or bend?
The slide lock spring either broke or was weak, and when he dry-fired the gun, the slide went forward off the frame. Early slide lock springs were thinner and more prone to breaking, sometimes they break in such a manner that they leave a broken off piece in the frame that can't be removed, preventing a new one from being installed. In some cases Glock has replaced the whole frame because even they couldn't remove the broken off piece.

The newer slide lock springs are thicker and less prone to breaking. They can still break but it's pretty rare.

Welcome to the Glock Forum biohazard2m !!

Which spring set did he order...?!
I will find out more info when I can and update you. Thanks for all the great info and pics.

This is not an uncommon ocurrance. But did you realize, the gun continued to function flawlessly until the trigger was pulled on and empty chamber.

Yea stuff breaks all the time but the good thing in this case is, the gun continues to function.
Don't get me wrong, I'm not knocking Glock. Besides this one occurance, the gun has never failed. And I realize that this is a minimal problem, I just wanted to get some feedback on the situation. I was just glad to hear that this is a known issue that can be easily addressed.

;)NO offense taken, just wanted to enlighten the readers a bit as to what was happening and what results to expect when/if you had to rely on the tool for protection or match results.


The same has happened to me in IDPA on a rainey day. I likened the events that followed the pull of the trigger to watching a train (in slow motion) come off the tracks and over the cliff!

I had another slide lock and spring in my gun bag for backup. Lucky me cuz I never did find the slide lock either! Had we not had so much grass and mud I might have.

Thanks for pointing out the problem of the broken slide lock spring situation and remember, Glock will most always make it right when it comes to their equipment.

Just a quick update, no part yet. The shop says spare part shipments are down because gun production is way up. I'm guessing its due to the election. Still in a holding pattern..
This spring (part# 2317) will only work in a Gen3 19,23,32,38, it will not work in a Gen4 or any other model.

The Gen4 19,23,32 actually use a different slide lock spring, part# 8073.

If your father calls Glock, speaks to the Warranty Service Department, and explains what happened they may actually send him a slide lock spring for free. Normally they don't send parts to non-Armorers, but some of the early Gen4 G19's had weak slide lock springs and the same thing would happen with them, Glock would send the new spring to the owners to install themselves.

Make sure when reinstalling the slide lock that the part of the slide lock with the groove in it is facing away from the muzzle:
