Have a glock 17, w/ glock 3.5 disconnector and extended slide stop. Have fired only about 100 rounds since last cleaning. I did not take the slide apart to clean it last time. I was cycling the action and noticed after pulling the trigger the striker was still in the forward position when I opened the slide. It will remain in the fired position (protruding) while the slide is pulled to the rear and then for most of the return forward travel until only about 3/4 of an inch is left before the slide completely closes, then it snaps back. It is not permanently "stuck" forward, a finger press on it pushes it back into the slide with a little pressure, but it does not pull back like I am working with a spring. This concerns me as it could theoretically set off a round before chambering if it gets stuck forward.

I will pull the slide apart and clean it, could it be just gunk in there, or is something else wrong?  I need to know what retracts the striker after firing (because it is not happening) and what should I look for when I pull it apart as far as missing/broken parts?

Thanks

no it won't. as the slide goes forward, the firing pin end will catch the end part of the trigger bar and resumes position.

mine does it too, dont worry about it.

I noticed the same thing with mine after I cleaned it. It is normal. There is nothing wrong with your gun.  Here is a tread on Glock Talk about this.


Cut from Glock Talk Thread

Yup, it's quite normal.

After firing, the firing pin isn't retracted like it is in most guns, the firing pin spring pushes it forward, not backward. After you dryfire it to field strip it, it's lightly pinned there in the forward position by the firing pin safety. When you pull the firing pin back manually, the click you hear is the firing pin safety snapping down in front of the firing pin.

When you fire the gun, the firing pin is pushed back by the primer of the cartridge you just fired as it slides down the front of the breechface during the unlocking of the action. Note that the spear shape of the firing pin nose allows this to happen without damaging the firing pin.

At any rate, the firing pin would be pulled to the rear by the trigger bar when the slide closes.

The striker has a vertical piece or "finger" that hangs down. This finger catches the top rear part of the trigger bar as the slide travels forward into battery.

Here is a good graphic of the Glocks action.

ETA: Click on the Visual Controls tab.

Then if you hide the receiver, slide, trigger mech housing, locking block and magazine you can get a good visual of the movement of the trigger bar and striker during the "cocking" action.

Clicking on the "+" and "-" tabs will shrink or expand the image.

HTH.

Thanks - I don't know why I never noticed it before - I searched glock talk but used "striker" rather than "firing pin" -

FWIW, if anyone enjoyed the flash animation of the Glock on sniperworld.com, there is a similar one available on STI's web site of the 1911's action. This one is a screensaver. It's not as customizable as the Glock one, but it's cool nonetheless.
