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

[wagon]

Jocko, I took the barrel out tonight and get it ready to ship tomorrow, upon looking closer, there are 2 hairline cracks extended from one of those "discoloration spot" to the side of the lug.. seems to me to me that "discoloration spot" is some sort of impurities in the melt and the hairline crack is the boundary which started to get worse (heat and pressure from firing). I'll provide the additional pix to Kahr, too.

The discoloration in that one area on the outside is nothing at all and if it was only that I am sure they would not replace it .

As I posted earlier, I put the barrel from my new PM9 with defective plating in the chamber in the mail to Kahr on Monday. I sent with Delivery Confirmation, and checked the Post Office web page this morning; the barrel was delivered to Kahr yesterday.

I called Kahr Customer Service to check status a few minutes ago. I was advised a replacement would be going out today or tomorrow.

That was welcome news, and very good customer service given circumstances. I would characterize my two conversations with Kahr folks as polite, efficient, and professional.

my sources inside kahr, they will replace any barrel with flaking of the nickel finsih in feed ramp and inside the barrel. There is no two week back log of barrels either. They have plenty of new kahr barrels in stock and it is a vendor issue. That is one of those things that they themselves don't know there is a problem until the barrels are shot somewhat to cause this finish which is in the minute thousands of an inch of thickness to flake off.

Kahrs customer service has went from what was way in the past of 4 or more weeks to get a gun back to now around 6 day turn around once it hits the kahr doors. One of the best now in the industry.

Thanks for sharing the very encouraging news, Jocko.

Thanks for sharing the very encouraging news, Jocko.

I didn't live with the FARC's either, so what do I know

Jocko, do you know if the plating issue has been addressed on the new barrels? The reason I ask is that the new barrel they sent me 3 wks ago started flaking after the first 100 rds. They are sending me another new barrel from the batch they just received. I hope the vender has resolved the issue on the new batch of barrels.

[jocko]

that is a good question, that I cannot give you an answer on...

To those member who has the same flaking problem with the Ni plating, do you use Ammonia based solvent in cleaning? e.g. Hoppes #9? I've heard these chemicals can cause flaking / peeling.

I believe I read somewhere about Hoppe's Elite should be fine since it is does not contain ammonia.

I use some spray nitro bore cleaner. It removes copper and metal fouling. It says it is safe on all barrels and does not contain acid. I do not see "ammonia" listed as an ingredient.

Kahr received my barrel on Thursday (10/22) according to the tracking number history. I'll give it a week and see if they call or if they respond. Seems like they are replacing the barrels.

They will replace it. They will ship out a new one usally within a day after reciveing it.

kahr

people tell me this is a vendor issue and not an issue with any solvents. just go clena the gun the way you have in the past. They will replace any and all barrels that are flaking the finish.

just shoot it likeu stole it..

Is the plating problem a cleaning issue at the factory?

replacement barrel arrives

Per earlier posts, I had returned my PM9 barrel to Kahr last week. Sent last Monday, arrived at Kahr last Wednesday.
FedEx Ground brought the replacement barrel this afternoon.
I literally went over the new barrel with a magnifying glass. Slight blemish to side of ramp at throat. Polished this out (well... mostly out) with 600 grit followed by Flitz. Look hard and you can see it. Small chip from machining in slide stop hole; a couple of light strokes with a mini-file and this was taken care of. Slight spotting inside chamber, but this rubbed out with Flitz; think it may have been dried residue from cleaning after plating.
Fit was good. Function check was good.
Not sure when I'll get to range, but with luck this week. Will report.
Stay safe.

Sent mine last Tuesday, and Kahr got it last Thursday. Maybe I'll get something soon.

good news, and REALLY BAD NEWS

Slow day, so I made it to the range. Shot a box of good quality FMJ practice ammo and then shot about another 50 rounds of mixed defense ammo to see what worked. Everything worked, Ranger, CorBon DPX, Gold Dot, even some old Black Talons I had. The weapon shot everything without so much as a hiccup. My confidence in the weapon soared.

Got home and broke it down and dry swabbed the barrel out. No solvent, just dry patches.

When I inspected the chamber I detected what I believe is flaked or imperfect plating. I cut a q-tip in half and used the paper shaft as a "feeler". Sure enough, some rough spots deep in the chamber. You can see the affected area and feel a "edge" around the extent of the rough spot, albeit certainly no thicker than a thin piece of paper.

I had inspected the chamber before I shot. I had seen a bit of a line but it looked like a line of dried solvent or some liquid deposit. It was not rough nor was there the "edge" to which I refer above.

It almost looks like it could be polished out, but I am not going there.

I called Kahr about 3:45 PM and was on hold 20-30 minutes, but never got to a CS person. So I get to stew in my own juices all weekend and I'll call Monday.

To say the obvious, this is frustrating. As nice as it was to get a replacement barrel 8 days after I sent the defective one in, to get one back with the same problem is not acceptable.

So... how many barrels like this are out there with owners who have not noticed?

And the question I am really asking myself, is how many times am I going to have to send a defective part back only to get a defective part in return?

Kahr needs to get on this and fix it. There was a guy here in NC that was specializing in 6.8 AR's. He got a bad batch of plating of barrels and it bankrupted him.

uh oh ... pls keep us posted.

Singlestack: have you received your latest replacement yet? If so, have you shoot it and do you have the same issue with LDM's?

I'm waiting for mine.. and may be I should just wait some more.
