Glock problem help

**Stubby** · 09-14-13, 20:20

Just purchesed a glock 17 gen 4 last week and took it out to shoot today, when I set up to shoot I did my normal trigger pull, slow, consistent to the breaking point and lone behold it shot 3 bullets out on one trigger pull, thinking maybe I was hasty with the trigger and accidentally bump fired it I repeatedly tried again, with the slow pull it did it every time, several magazines later I figured out that if I quickly jerk the trigger "improper I know" it will only fire once.. I'm at a loss here, I myself shot it, my father and a family friend who is a LEO shot it with the same results, I plan on calling glock this Monday to sort it out, has anyone else had this problem? And no it isn't over lubed and has no aftermarket modifications done to it.

That's DEFINITELY in the "bad thing" category, and you need to send it back to Glock ASAP. Do NOT let them talk you into you paying for the shipping - not on an issue like this.

I'm going to assume you didn't do the ".25 cent" trigger job - I've seen people over polish parts to the point where metal was removed, sear engagement was out of spec, and the pistols would go automatic...

Regards,

Uh, there is definitely something wrong. Send it back to Glock ASAP (and obviously do not lend it to anyone in the mean time).

Pics of the internals of the frame and slide would be great. I'm curious to see what the "crucifix" on the trigger bar looks like.

Keep us updated on how Glock handles it and what was the cause.

Good luck with it.

This is a joke ...right

Glock will take care of it, if you have internal pic we may be able to give better pointers.

This may be a stupid question, but is it even possible to over lubricate a Glock?

Check your firing pin safety. Push on it to see if it freely moves and is under spring tension to return to its original position. If the firing pin safety spring is not properly secured in the recess or the firing pin safety gets bound up, the firing pin will slam forward under recoil and with enough inertia impact the primer to cause the next round to fire while you are holding the trigger to the rear. This is not common, but has happened before.
