Glock 19 + HS507C not going into battery (locking NOT on empty)

[rodralig]

1. First - I checked if I were limp wristing. So, I consciously focused on my grip. No good.
2. Second - magazines. I switched between magazines (15-rd vs 10-rd). No good.

internals are ALL OEMalso be said - this never happened before I added a red dot.

TIA!

Do you mean that the slide stop lever is activated? Like when you have an empty magazine. But happens when you still have cartridges in the magazine. Trying to get a better picture.

Correct! It just locks up like it is empty.

Did you check if you install the slide stop spring correctly?

Sometimes optic can mess with things. Try a heavier recoil spring

Is it newly ceracoated too? Could be it is too thick. May fix itself in 200 to 300 rounds

If the slide stop is locking the slide when shooting, and the mag is not empty - it can only be a few things:

- You are doing it with your fingers/hand unknowingly
- The slide stop spring is weak or damaged
- The slide stop spring is installed incorrectly

And this could be affected by the weight of bullet which does influence recoil. When the slide stop spring is installed incorrectly, it will lock the slide intermittently depending on how much bounce it gets. And more recoil can influence what happens with your grip on the gun.

I would remove the slide, and flick the slide stop up and check to see that it returns back down with authority and speed. Keep checking it by flicking it up. If it does not return down with good spring action, then inspect the spring.

If you want to know if your hand position / grip affects the problem, then shoot one handed with your left hand.

Yes. If the slide stop spring goes under the top pin then it's installed correctly. I was thinking if the spring is installed incorrectly then it doesn't provide enough spring tension to push down the slide stop and it might bounce up and lock up the slide when the gun is not empty.

That is my guess. That is essentially the only thing that had changed from a perfectly working pistol. But what keeps coming back to me - why the hiccup with a heavier round?

600-rds as of tonight.

That said, never had this issue post-Cerakote up until tonight.

Yes, I thought the same of the first, thus, I did some strings with both my thumbs flagged up that they don’t touch the slide. Then again - why with a particular kind of ammo. I have gone through 60-rds of 115gr tonight and not a single hiccup. Yeah, I know - I am so hanged up in the ammo. I guess it is the only thing I see different.

As for slide stop spring - never thought of that… But this is a “young” Glock - less than 5K rds. Regardless, I have spares - I will just replace them.

Oh! I actually did that. Spring looks good. Regardless, I am replacing it.

Not shooting with the left hand - but actually shot with the web of my hand so low down from the tang. Even that was inconclusive.

A recoil spring or optics or whatever should not affect that slide stop staying down. That is completely the function of the slide stop spring, and it should have more than enough power to hold that slide stop down no matter what else is going on with the gun.

Makes sense. Slide stop replacement it is then for now. I will try again.

147 grain bullet shape is slight different.

I blame new ceracoat. Should work itself out fine

How? How could a Cerakoted slide be a potential problem as related to the shape of a 147gr bullet and/or a hollow point round? The shape should only be impacted by the feed ramp of the barrel?
