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

[Bawanna]

I'm not aware of any aftermarket barrel. I think the best thing to do despite your negative impression of the Techs response is to politely request a return shipping label.
Painful as it is to have them gone for a spell they will most likely come back with new barrels and ready to make a positive impression once again.

There isn't a thing wrong with the barrels that you have. It's no different than the wear marks that appear on the barrel hood. The nickle plating is only from .0005 to .0015 thick. It won't impair function in the least. The wear is strictly a cosmetic issue.

+1 for Muggsy

The plating is there for its value in "lubricity", preventing galling and wear.

The plating will be "gone" from the barrel after not too many shots.

The plating on the ramp and chamber is because of the process, not because of intent. Its easier/cheaper just to plate the whole barrel.

And the plating does wear. My old PM9j was flaking at the ramp, and never hiccuped.

My bought new PM45 had what I thought were lead streaks in the barrel, but... this turned out to be nickel plating. I scrubbed it like hell, thinking it was lead, but after a couple of boxes of ammo... I was wrong, it was nickel, and it had been blown out of the barrel from shooting.

I hate to say the plating is "cosmetic", but will say that Kahr has not explained things well enough.

Its a non issue, like Muggsy said.

Cosmetic as a scratch on he frame that doesn't impair function would be considered cosmetic. A little Flitz and a Dremel will make that ramp look like new.
