Is this normal wear for a Glock 19

I am new to the TFL and to Glocks. Bought a new G19 Gen 3 about a month ago and noticed this wear on the plunger, (not sure what it's called), mechanism. I was wondering if the Glock experts have seen this or if there is any need for concern. It appears that the plating has worn off where the trigger mechanism contacts the plunger. Here are some details.

Have fired about 800 - 1000 rounds through it. Have only shot factory loads, specifically Winchester, white box 115 grain.

Have cleaned it after every range session with CLP or a clean scrap of T-shirt and a nylon brush. Lube per owners manual.

Is this typical wear? Thanks for your help.

That plunger is the striker block safety. Unless it is depressed by the nub on the trigger bar, the striker can not travel forward enough to hit the primer on the cartridge and fire.


Glock uses an antiseize compound on their firearms during assembly. This compound is copper colored.

If you do not completely remove the compound befor using the pistol, the compound can varnish the parts and leave the copper colored look you see.


Your pistol looks practically pristine... So no worries. I don't know if you are cleaning meticulously or if you cleaned it up for the pictures... Either way, know that meticulous cleaning is rarely needed in a modern pistol like a Glock. I clean every few hundred rounds at most. I will go several range trips before cleaning most of the time. I do clean defensive weapons more often though.

What I am saying is... Don't worry, go out, shoot and enjoy the pistol.
 
FWIW I think it's okay too.

Got to complement you on the pictures. You're really showing us what you're talking about. There are many folk new to the forum that have problems getting pictures posted at all--let alone clear, nicely sized ones. Nice to see it can be done.

Exactly right. Your "new" Gen3 19 could have been sitting around in its case for awhile, so that copper anti-seize compound can harden & discolor those internal parts.

The two Glocks I have now were both bought new within a couple months of the S/N born on date so I never saw that kind of discoloration. It sounds like your gun is cycling reliably, so I think you're fine, you can always call Glock CS to confirm.
 
All,

Thanks for all of the good information. One thing however. For certain, all of the original copper anti-seize is long gone. The copper you see on the striker block safety is in fact the base metal plating beneath the finish. You can feel the difference in the surface of the metal when you rub your fingernail across the top of the plunger. This is where the trigger bar rubs across the surface. I was just curious if this is normal wear. Admittedly, not many rounds have been run through this gun especially given what everyone has told me about the abuse these guns can take. Just wondering if they all do this.

This is a great forum with lots of awesome information.

The base metal of the striker block isn't copper though, unless the coloring you're seeing is the result of the application of the finish. I've actually had the same phenomenon happen to a Glock 19 I own, and yes you could feel the difference from where the plating/finishing was removed. Mine was a different shade of silver, however.
 
Use a light grease on the slide rails, striker block plunger, and outside barrel surfaces.

You don't need a lot, just a light coat, grease works better on those areas, sliding/shear forces, and you won't need worry about wear.
 
The Glock was the only pistol I had that issue with in regards to the plunger, in 70 something pistols. Oddly it was just one Glock. Maybe a batch where the coating wasn't quite right? Nowadays I use the APEX plunger which is solid stainless so there's no flaking. But again, it never caused issues anyway.
 
Glock Copper Color

+1 on all replies^^,all my Glocks exhibit this.GlocK says to let the copper wear off naturally.Your gun's fine. :D
 
That is not the copper colored anti-seize lube you're seeing. It is a nickel or similar plating flaking off. I was an armorer for a police dept. and started seeing this several years ago on the firing pin safeties and trigger bars. The plating is sometimes very sharp as it peels away from the base metal. I called Glock to advise them as to the peeling I was seeing and to inquire about why they were plating these parts and what with. The person I spoke with denied they were plating any of the internal parts,etc. Kinda like, "Who you gonna believe? Me, or your lying eyes?" I still don't know what they were plating the internal parts with, or why, but the peeling I saw was to such an extent that I replaced these parts in officers' guns when they came through the armory. I don't know if they are still plating internal parts, but regardless of the denial I received, they certainly used to.........
 
It's called the firing pin safety. As rock said, the plating coming off is well documented. Doesn't happen on all Glocks all the time, but there was a OIS shooting where the deputy was killed because of a jam caused by a good size flake of plating getting stuck in there. I had a G21 with the same issue, but just used a Scotch brite pad to remove the plating, and polished it up.
