G 17 metal peeling off of internal parts

I have another thread asking about making a glock more accurate then stock and while i was polishing parts for the glock .25c trigger job i noticed that there is a thin shiny layer of metal peeling off spots on some of the internal parts in my gen 3 g17. The worst spot is on the back rails on the lower part of the frame. There is the same issue on the metal piece under the extractor and on the trigger bar. Has anyone else had this happen to their glock and what did you do? I am going to contact glock and see what they say. My g17 has been 100% reliable so far.

 

Pics?

Best thing to do with a Glock is shoot it.

 

I am not home to take pics now but i will post some later

 

Glocks are inherently (and practically) more accurate than most owners or users may ever be able to realize. (Like other quality pistols made by the big name companies. )

Perhaps more owners/users might benefit from more training and developing a good foundation skillset, and from the opportunity to engage in more frequent proper practice. Shooting is a perishable skill, you know.

I shudder every time I hear or read about someone doing their own "trigger job", especially the "Glock 25-cent trigger job", a "fluff & buff", etc. Not needed. May cause problems.

Many of the smaller steel parts in Glocks have received some type of plating finish. It's varied now and again over the years. I thought I remembered from my last armorer recert class that they've been using a version of Teflon Nickel in recent years.

A couple of my own Glocks produced from different years exhibit a copper plating layer seen under the finish on some of the steel parts (rails, locking block, trigger bar cruciform, firing pin, etc).

Minor flaking usually isn't a functioning issue (although some folks may consider it an annoying cosmetic issue). If it becomes excessive in the firing pin safety plunger channel or the firing pin channel, it might require parts replacement (consult a local Glock armorer or call Glock).

Just some thoughts.

 

The parts you're describing are nickel plated. The steel is first plated in copper, and the nickel is deposited on top of the copper.

Do you clean these parts in a bore cleaner by any chance? Hoppes #9 eats copper. Exposing a nickel plated gun to bore cleaners can make the plating flake off. Same thing could happen with Glock parts, particularly if you're polishing them. I've tried it, and the 25 cent trigger job did not improve my first Glock's trigger a lick, no matter how hard I tried. I eventually wore through the nickel and the trigger pull got a tiny bit worse. What did I do? I went to LWD's website and replaced those parts.

I think the 25 cent trigger job is bunk, because the nickel wears in so rapidly, anyway. If you think you're going to stone the parts to make the contact areas perfectly flat, you're mistaken. The coating will wear away. If you polish them just lightly, you're still not removing high/low spots that ride over one another. The only way to do that is to work the trigger. The trigger will break itself in, and it doesn't take long at all. In retrospect, I'd put a tiny bit of fine polish on the trigger bar/connector interface and work the trigger 20-30 times before I'd take a qtip to the parts and hand polish them.

As for the slide rail, I'm not sure if that's a big deal. I think it's just one of those things that eventually wears through and the gun will keep on ticking. Not a big deal for the internal parts either. I would replace them only if it's affecting the trigger pull.

 

I've had some plating wear/flake off of the firing pin safety plunger before. I've seen pictures of it wearing off the trigger bar. In both cases it caused no problems.

I would say if you aren't having problems it isn't a problem. If you think a bit of preventative maintenance is in order replace the cheaper easy to replace parts with new Glock OEM parts. If it flakes off further I would probably replace the offending parts.

 

If you can't hit a target at 230 yards consistently with your stock glock then it's a shooter issue and not a pistol issue. YouTube hickok45 230 yards for a eye opening video on the accuracy stock pistols are capable of with cheap ammo.

 

It does look like a nickle plating that is coming off. I didnt know bore cleaner would effect those plated pieces but in the future will avoid getting on the internals. What cleaner is safe to use?

 

Glock

I've owned many Glock's. My opinion is that a Glock that's been messed with is almost always a LESSER pistol. A stock Glock, in my experience, is a Good Glock.
Your mileage may differ as the auto makers say.

Normal. They all do that. Mine started at about the 1K round count.

 

Nothing to worry about.

 

My G22 trigger started out as something that could have been more, but right around 200 rounds it broke in enough to become quite pleasant. Because of this, I stopped considering an after-market trigger, but I am going to file down the trigger-bar safety flush with the face of the trigger (when the trigger bar is depressed, of course).

Plating wearing off? I've had it happen. Cosmetic. Annoying. Glocks still ran.

 

I use bore cleaner for the barrel and CLP for everything else that needs it.

 

Whatever's causing the plating to flake off, it's probably not bore cleaner. I was doing the "$.25 trigger job" before there was a $.25 trigger job. None of my Glocks exhibit flaking of the plating. All of my Glocks' triggers pull a lot better than they would have, had I not done a judicious polishing of all the mating surfaces of the firing mechanism. I don't use Q-tips...that's just silly. I use a Dremel, Simichrome (very fine polish), and the polishing attachment that requires attaching a cylindrical, soft, white pad to the mandrel. I also run the Dremel on low speed.

I always install aftermarket connectors in my Glocks. I don't like the feel of any of the Glock factory connectors. Recently installed a Glockworx 2# connector with competition spring kit in my nightstand G17. Trigger pulls GREAT @ 2 3/8#.

I'm happy to say that I'm NOT a certified Glock armorer.

 

I just got my 3.5# connector and extended slide release yesterday gonna install hopefully today. Other then that i think i will leave the glock alone for now...other then shooting it of course! I think i am going to have some work done on my 1911 next.

 

By the way what are the advantages/disadvantages to a new spring kit in a glock?

 

You can lighten the trigger beyond what a connector can do with a spring kit. The disadvantage is that it may cause light primer strikes (depending on which spring kit and what ammo you use).

 

Plating isn't supposed to peel, it's supposed to evenly wear. The plating has peeled off of those parts after just a few hundred rounds in some cases, suggesting that the plating process wasn't done correctly because that shouldn't be enough time to wear down to the copper undercoat to allow it to be undermined by a solvent.

I've used Hoppe's Elite Gun Cleaner on my Glocks' nickel plated parts with no adverse affects. After cleaning them and drying them, I wipe them down with Ballistol oil then wipe them dry to give them corrosion protection. Even though they're nickel plated, there are spots where the copper undercoat and steel have been revealed through natural wear so I like to wipe them down with oil.

 

Mine G17 started to do this also after about 1,000 rounds. It really hasn't effected anything, and the trigger pull is now butter smooth.

I find Glock triggers to be great out of the box, and with a few hundred rounds they really start to shine. I haven't felt a need to mess with any of my three Glock's triggers.

 

Happened on the upper surface on one slide rail on my G19. Polished it with 600 grip emery cloth (to the point where a fingernail wouldn't catch) about 3,000 rounds ago and it's hasn't changed appearance or feel since.

I called Glock and they said if it ever got to the point it was causing problems they had it noted by S/N and they'd make it good. At this rate my grandson's grandson may have to take care of that if at all.

It's the rail on the right. Looks rough but it's actually smooth as glass and won't catch a cotton ball so I'm happy. Gun runs fine and I got a plan.

 

Mine has gotten to the point where my fingernail does catch the flaking plating on the frame rail so i might take ku4hx's advice and use some 600 grit emery cloth and remove the high spots. Thats great to hear that glock customer service will take care of the issue if need be.

 

Fogot to add that i just changed out the connector to the 3.5# connector and the trigger is much smoother. It feels like the wall you normally hit after the take-up is gone w/ the new connector.
