Sooooo... I built a g19 on a p80 frame. I am having FTF, stove piping, and weak primer strikes. I installed a threaded bbl with comp, and red dot, the slide is brownells with lighting cuts. Thinking I may need a reduced power power spring? But the weak primer strikes worry me. I installed the striker channel liner but I was unsure if there was one already present. Everything I read said some come with it and some dont....not sure!
If anyone can take a look and help me out it is greatly appreciated!!!
Thanks

Is that FTF failure to feed or failure to fire?

Was the p80 an 80%?

To install 2 channel liners you'd have to hammer that second one in. You would definitely know if you had two. Unless they can somehow stack one behind the other. I'd have to disassemble a slide to figure out if its feasible. Likely not your problem.

Did you lube your firing pin?

Any chance you have another G19/23 laying around that you can start swapping parts with?


And I am sure ViniVidivici will be by shortly with some more insight.

The right answer to this is "no."

An oily striker will get dirty and cause things to start gumming up.

Oh, I know. Just seeing if he did.

Did you read my post in the what did you do today in the firearm forum? Police tradein Glock 22 came with grease in the firing pin channel.

Haha, no I haven't seen that . . . yet.

Long post, somewhere towards the end I mention it. In hindsight I should have taken pictures before I did any cleaning. So people can appreciate the magnitude of grease in that gun.

Poor Eric is going to come back to this thread thinking he has a bunch of responses. Nope just us bantering back and forth lol

Good for Eric, he should just fix his problem lol… he might be grumpy for a bit lol

Bring that thing to the shoot next month, we'll have a look at it. Some of us are going up this weekend too, bring it!

No way you've got 2 channel liners in there, like Stompah said, you'd know it.

I have 2 Brownells slides. They are fantastic. They are a bit tight when installing the liner, it might not be all the way in. This would prevent full travel of the firing pin.

Certainly compare it to an OEM slide assembly, see if the liner looks to be fully seated, see if firing pin protrusion is same.

Are all internals OEM?

I wouldn't go straying from OEM spring weights just yet. Many folks have built P80s that run 100%, going with standard spring weights and OEM parts.

It's possible putting the comp into the equation is throwing things off. Some folks DO have to change recoil spring weights to get them to run right with certain ammo. Some will only run 100% with hot loads.

I'd also want to know if it was an 80% or factory frame.

Many parts to the equation, but it is solveable!

Nice offer !

First thing I'd check is the striker channel - make sure it is clean and dry, like others said. The channel liner should also be OEM; I had issues with aftermarket.

Another thing is the rear slide rails and locking block, since this is a P80 frame (I assume 80%). They don't always sit where they're supposed to. If the slide is dragging, there should be indications of this in the form of rub marks. Sometimes, one side sits high, so the slide drags there and doesn't go all the way into battery.

I would also pop the slide off, remove the recoil spring, and see if the spring slides freely in the channel on the frame (manually). If it doesn't, it may be preventing free movement of the slide, and you may have to open that channel up a little more.

Yeah, that's true, there can be issues with the rails on those things. Helps to have a stock Glock alongside to measure and compare slide to frame gap, etc., with a micrometer

Also yes, the channel for the RSA is an area of note, has to be perfectly clear and cleaned up.

thanks all!!! i will dig into it when i get home this afternoon. i will definitely identify all points of interest and report back.
thanks again

Look into replacing the Polymer 80 trigger assembly. My slide was hanging up when the trigger was held back during return to battery
I used an Overwatch Precision Polydat trigger kit. Nice upgrade. The Polymer 80 trigger assembly has too much flex.

Come to think of it I wonder if my issues with my Glock 23 upper on the SCT frame and SCT internals are due to the SCT internals.

I have parts. I might do some swapping tonight.

Very likely. Alot of the issues I've seen folks have are due to not using ORM Glock internals for small parts.
