Hey guys wondering if anyone could possibly help me out. I've started to have light primer strikes in both my glock 17 and M&P and was wondering how to rectify the problem. I'm not sure why it's happening, although I suspect I may have gummed them up with a bit too much frog lube (which I will likely never use anymore). I did a complete disassembly of both and cleaned them down good with hot water, then isopropyl alcohol (90%) and then Mpro7 cleaner and oil. They both still seem to have the same issue however. Any ideas on what could be causing the problems or how to fix them? Any help is appreciated.
 
froglube = coconut oil apparently

are you noticing this in an outdoor range by chance? As the temperature cools... one can imagine the coconut oil gumming up more.
 
In you last cleaning did you clean the firing pin channels of both guns or did you just do a regular fired strip? You should regularly clean these channels (I do mine every 1,000 rounds or so) and keep them fairly free of lube.
 
If you're trying to shoot Barnaul, it's the ammo. I had a misfire with that ammo on the first shot out of the box with a new Glock 19. I've learned it's great ammo for practising immediate action drills, sometimes it goes click, others it goes bang. If it isn't the ammo, then disassemble the pistols, take out the strikers, dry them off, dry the channels they go in, and reassemble - do not lube the striker or striker channel of any striker fired gun, excess lube can cause them to "pump" instead of strike.
 
For the Glock - There should be zero lube in the firing pin channel. If you take the slide off and with the firing pin lug pulled to the rear you should hear it click. Let the lug go forward. Shake the slide back and forth , if you don't hear the firing pin moving back and forth you have an issue. Push the drop safety button with the slide facing down. The firing pin should drop free of the breach face.
 
Barnaul.....it's the only thing that made my g22 stop running...they have notoriously hard primers....I came here and asked the exact same question...
 
Have you cleaned the striker channels and striker assemblies thoroughly, down to the breech face?


FrogLube is complete crap, stay away. Natural lubes don't hold up in the long run, even Fireclean gets thick and sticky after sitting a while. That and they're a horrible company.

I never understood the snake oil lube fan boys. Military grade CLP works fine on all pistols and AR15s, only time I differ is on MG's.

Yea.... some one finally said it! I've got a gallon of that stuff. Guess what I'm using for the next 10 years, love it.

Sadly no MG experience though.

If the striker channel is dirty/fouled, it will slow striker velocity enough to light strike.

On the topics of lubricants, I use PTFE or moly bearing grease on the slide, frame rails, and barrel, and CLP on everything else.
 
Yeah I took the striker assembley out and cleaned all that that as well in both pistols and the ammo was Sellier&Bellot factory ammo. I'm not sure if it was the frog lube or maybe dry firing (something I hardly ever did) that might have caused these problems. I think I'll try putting in a new firing pin spring in the glock at least and see how that works out.

I have a 20 yearold glock 26, and have been dry firing the #### outta it last couple days... Not one single issue has occurred. I'd try some quality ammo and see how it goes. I also used to dry fire the #### outta my M&P too.

How are you lubing your pistol? Are you using oil on the frame? The only parts I lube is the barrel, slide hood and frame rails/slide rails, and trigger bar where it rubs on the connector. The rest of my pistol goes dry.

Good guide here

X4 or 5 on Froglube entering the firing pin channel. The exact thing happened to by G17Gen4. Being a 1911 guy, when I first bought my Glock (first polymer striker fired), I didn't understand that unlike a 1911 or AR, a Glock is run dry aside from a very few locations that need but a drop of oil. Think like 25% the lube of a 1911. Anyhow, long story short, someone sold me on the idea of frog lube and I bought and used it on my Glock (inclusive of the firing pin, ask any 1911 guy if the firing pin and spring in your gun should be wet?). Bad move, the channel became gunked up slowing down the firing pin enough to light strike the primers...all primers (I tried 5 different ammo makers).
Dry firing won't cause it.

Sellier&Bellot is pretty good quality ammo.
