I had an old beater Glock 22 Cerakoted not long ago, and yesterday had a sobering problem rear its head. I was shooting on an indoor range, and the a/c was turned up so that it was really cold inside. The gun started to have repeated failures to fire - two or three rounds per magazine. The primers were lightly dimpled, and upon rechambering, each round would fire fine. This was Winchester NATO M882 ball.

I disassembled the slide assembly, and when the firing pin assembly came out of the slide, the firing pin channel liner came out with it - it just slid out under light finger traction. Clearly, this is not supposed to happen, as the FPCL is supposed to be a tight friction fit in the firing pin channel. I have been a Glock armorer for 15 years and had never seen this before.

My belief is that the heat curing of the Cerakote (baking at 250F for 4 hours is called for by Cerakote) caused the FPCL to shrink a bit, and the cold a/c might have caused the slide to contract a bit in the cold as well, leading to the loose fit of the FPCL. Apparently, the FPCL sliding back and forth in its channel WITH the firing pin assembly, rather than staying still and giving it resistance, was robbing the firing pin of enough energy that it caused light strikes and clicks instead of bangs. As this is a carry gun, this was a dangerous condition of unreliability. I replaced the FPCL, and this fixed the problem.

Bottom line: if you have had your slide heated (as for Cerakote curing), check your FPCL to make sure it is firmly fixed in its channel. If needed, replace your FPCL with a new unit.

Happy Reliable Glocking!

This channel liner vs. cerakoting problem is common. Some remove the channel liner before the process begins.

The real lesson to be learned is: Don't apply the cosmetic clown paint known as cerakote to any Glock that has a serious intended function. There is absolutely no positive functional value to cerakoting and other such fluff, and there are some very serious negative consequences.

Get your money back from the moron who applied the Cerakote.

Thanks, but I like the look. As the gun works well now, I'll keep it.

 

[Walk Soft]

Most will remove the liner and fill the channel up with something before Cerakoting. I see all kinds of Cerakoted guns in competition that don't have issues and most of those guys are running reduced powers striker springs to boot.

 

[bigbrother1984]

I ALWAYS remove the channel liner. I have never had an issue.

 

[quantico]

Just one more modification to a glock that can have a negative effect on reliability. Be careful when you decide to modify a gun , especially if it is used for a defensive business.

 

[GRR]

I've had a couple of slides cerakoted with no issues. I did remove the channel liner and all other parts beforehand.

 

[Phelen_Kell]

Better refinishers will keep spares in stock because this is a common part to replace during refinishing if they bugger it up when removing before refinishing.

Wouldn't *common sense* tell ya to "remove all plastic/rubber parts prior to baking in an oven"....???
Key words "Baking(heat)...Oven"...:freak:

 

[MedicineBow]

I have neither experienced with mine nor heard of any Cerakote related issues with Lipsey's Cerakoted slides.

Or you could let it air dry for 24 hrs. It will cure just the same.

What? "H" series must be heat cured.

 

[Buckshot Barry]

Great post OP. Thank you.

 

[GeorgeMason]

I have a few cerakoted slides and have never had a problem. Whoever cerakoted it with the channel liner still installed should really stop doing that. The guy who does it at the shop I go to requires raw parts or charges a premium to disassemble.

How do we know the Cerakote guy did not remove the sleeve?

 

[bocadave]

I had two sides Cerakoted, a G19 and a G43, after some work was done by MOD 1. I was told liner was changed and could be checked as they use white ones to replaced so you know. Was told the G43 did not apply as they do not have one. I did not know that.

 

[mrmike7189]

I know a guy that did it himself in his backyard to his glock 22......sprayed it on too thick and the gun never worked right....he had to strip it down to nothing and reapply several times before he got it right. seems too hard for me, besides I dont want my glock to look pretty!

 

[ChicagoZman]

It's all in the skill of the applicator. I've had my 23 done a couple of times and it always worked great. But I've seen customer's guns done by another guy that boogered their guns up pretty badly. One had actually overheated the frame to the point it warped and was turned into junk.
