? about plating coming off feed ramp and chamber on PM9.

[jggonzalez]

Does this mean that Kahr has changed the steel in the barrel? I have an MK9 that is great and was considering getting a K9 to go with it. If they're using cheaper materials and plating them to cover it up, then I'll reconsider and go with a G19.

Now that's a good question.
Wonder if Kahr would be willing to respond.

Definetly interested here.....considering a K40 but I'm not at all up for plated barrels. My new production MK9 purchased June 09 is not plated.

i believe that they are nickel plating the newer ones. i had an mk9 that i bought a couple of years ago and it was polished. i got another mk9 in july and it is definitely plated. it looks like the bore is also plated.

I just bought a new TP9 and the barrel is not plated. Curiouser and curiouser.

Kahrs reply to plating.

My question to Bob Holmes at Kahr: how long has kahr been plating their chambers and ramps??

ANSWER; Since day one, All barrels have been plated with a nickel based coating.

So if u have a kahr that barrel barrel is nickel plated...

Interesting.
What would make the plating start to come off is the next question?
Improper plating process or something else?

Yeah, I agree....interesting. I've polished out minor tool marks without being aware of plating. And the OP's picture is definitely ugly.

I worked in electroplating for eight years.Usually if the plating started to come off it was poor adhesion caused by improper cleaning and/or surface preparation.The way it`s flaking off in the picture looks like it could be either or both. The metal looks odd underneath. I wonder if it was plated with a base metal and then plated with chrome or nickle. Maybe electroless nickle.Who knows?

Wouldn't this make you wonder if there was a bad batch of barrels out there somewhere?
Doesn't seem likely that only one barrel would turn up with this problem, however it's the only one I've personally heard of.

Hopefully it's just a one time thing.

I actually read about a plating problem at glocktalk. New PM9 barrel failure - Glock Talk I noticed a problem in the chamber of mine after the first or second time I shot it, but never thought much of it. When I was cleaning it before the last time I shot it, I remember a very small spot on the feed ramp, I just thought it was a blemish. Went back to the range and shot about 150 rounds and the plating came off rapidly. Probably a bad batch. I bought mine in march 09, my serial is IA92. I received my new barrel from Kahr today.

Double-u tee eff? Plating on a stainless barrel???

[jocko]

indeed

a bad plating job indeed. I can remember back in the days of chromed bumpers, Had alot of the chrome would just peel pff, due to poor plating. Not supposed to happen,but it does.

This is the first that I have seen in kahr's barrels. They would not know they had a bad plated barrel until it was fired some rounds. No doubt they will stand behind this flaw..

I just noticed yesterday that my PM9 barrel is peeling or flaking inside the throat chamber--not feed ramp. I have 425 rounds through it. I am not having any problems so I don't know if it's an issue to be concerned out or not.

Mine is a #IB07xx and got it in June '09.

Here are some photos of the nickel coat peeling inside the barrel chamber. I will send to Kahr and see what they say.

It's hard to see but it's right inside the chamber throat.

Yesterday sent my PM9 barrel back to Kahr for replacement for rough spots and/or plating flaking inside chamber.

This is frustrating on many levels, but moreover because I bought my PM9 new a week ago.

Friday went to range to run the 200 rounds. Had three instances of not going fully into battery; a 1/8" or so from closure. Can't say this was from a rough chamber as I had not seen the rough spots then, but suspect it now.

While cleaning Saturday, first noticed the rough spots on the plating inside the chamber.

Whoever did the plating did not catch this, and then whoever assembled the pistol did not catch this. And obviously I am not the only person to have a problem. Reasonable guess there was bad batch of barrels.

So shouldn't Kahr issue some kind of advisory?

Stay safe.
