PM9 Cocking Cam Chipped

[Subverto]

Hi Everyone, I am new to the forums and unfortunately my first post has to deal with an issue with my brand new Kahr PM9. I bought the gun last week, followed all of the pre-prep instructions, and thoroughly looked the gun over while preforming the pre-prep steps. Despite having a very rough looking polymer frame, (plastic shavings all over the place on the inside of the frame, plastic rails with plastic burrs all over them, etc) everything looked okay. I took the gun to the range over the weekend and ran 200 rounds of FMJ for the break-in and 40 rounds of Gold Dot for a reliability check. Everything fired flawlessly with no issues.

Last night I took the gun apart to clean and while cleaning I noticed what looked like a small chip had been taken out of the Cocking Cam. If the rough polymer frame didn't already concern me a bit, this chip certainly doesn't make me feel any better. Below are pictures of the chip. It is kind of hard to see in the pictures, but clearly visible in person.









I have two question for you guys:
1. Is this normal?
2. Should I call Kahr about it?

Thanks in advance for you're responses.

Since this is your first post I must be thinking of someone else that posted similar pic but was concerned with rough polymer frame rails.
Yours look much better than his did for what thats worth.
Since that cocking cam works as a unit all the way across and not just on one little piece I'd not be concerned myself, especially since you mention that it shot flawlessly.
I you know for positive sure that it was not chipped in anyway prior to shooting I'd look it over after your next shooting session and see if it gets worse but I suspect it won't. I think I'm looking at the right spot, right in the middle?

I'd keep shooting it myself.

Welcome aboard.

Actually the chip is on the upper right corner of the rear cam. I guess my red circles didn't really show that very well. I am pretty positive this cam was flat all the way across on the top. Now the corner is chipped off. It is very rough on the corner now. Definitely looks like metal was chipped away, and not a clean cut. The fact that the entire tip of the cam is what is used for cocking is what concerns me, as there is now less surface area to contact the firing pin.

If it was mine I would.

After looking at my CW9 and CW45, it's my belief that what you are seeing is not a chip, but a machined/cast surface. It's my further opinion, that it's put there to provide extra clearance so that the cocking lobe will not, in any way, interfere with or prematurely activate the striker block. Of course, my opinion is worth exactly what you paid for it.

After looking at your pictures it looks like your cams are exactly the same as mine, albeit a little smoother. It looks like this is how they are designed like you said. I guess what threw me off is the cut out on my cam is very rough, which made me think it simply chipped off. It seems like you have solved the mystery. Can anyone else confirm that their cocking cam is the same as mine and Gregs? Thanks!

Mine looks like that, too. I'll bet you have a dent in your left rail, too... the metal one. That's normal, too. Some guys have gotten upset and excited about that, too.

Those are some gnarly pictures, Greg. You guys need to vacuum the loose stuff out, but not the parts!

I had some pretty good sized chunks come from just under the rear of the rails on my PM45. It looks like the slide batters the frame a bit there. I pulled the loosened chunks free and tossed them. The metal stuff holds things together.

Here are some pictures of my PM9, circa 2006. There are small gashes in the polymer just above the "dent" in the rail. That's an alignment mark or something used in manufacturing the frame.

Mine is the same and I'm confident it is by design.

Tip: canned air blows the lint off for better pics.

I added pictures of my PM9 to the previous post.

LOL, you guys are some harsh critics; my method, my art, my madness is just not appreciated
I've found that canned air works well for freeing stuck threaded parts; apply heat, then invert the air can and spray. Sometimes it works for removing dents in sheet metal.

I used all of mine up on my old irrigation pump. It overheated and shut off. I sprayed it with the inverted can. It took almost a whole can, but I got the pump working and left the top off the dog house it was in to keep it cooler.

that is not a chip, it is there by design, just shoot it like you stoleit and welcome to the forum, we may not be the bestbut that is our goal.

PS. I am holding a new one in my hand out of my parts box and it has that "chip".

[Subverto]

Thanks for the quick replies everyone. It seems I jumped to conclusions on this one. I feel much better knowing that my pistol is fine after having spent almost $80 on ammo to break it in

[jocko]

if you dont ask, u will never know either, so it is not a foolish question. Now just shoot it like u stole it..

You never said nothing to me like that and not being foolish. I seem to recall a comparison between my brain and a box of rocks. I felt so foolish.

Ok maybe I'm just foolish, self centered and paranoid. So glad I brought my binky today, my thumb was getting very sore. At least I"m not curled in a fetal position on the floor.
