I bought a new CM9 today. Took it apart to clean it and cycle 200 or so times. I noticed lots of black polymer shavings. Is this normal? Should I be concerned?

No.......The slide rides on the metal inserts, the plastic rails are more of a guide than anything.......

Even though it is polymer, do you suggest using grease or oil on a brand new CM9 slide.

Only need to do the metal insert rails.......choice is up to you. Both will work well, most just have a personal preference as what they like and are used to.

I was looking at magazines for my cm9 and I see a standard and covert advertised. Anyone know what the difference is if any? Thanks:huh:

I haven't fired my CW9 yet, but I disassembled it as soon as I got it and cleaned/lubed it. It to had quite a bit of polymer shavings. I reassembled it and racked the slide 200+ times. Then I disassembled it again and cleaned/lubed it once more. It had a few polymer shavings the second time as well, but nearly as many. I wouldn't worry about them, as I think that is fairly normal. However, I would keep them cleaned out of the internal areas so they don't build up over time and cause issues.

The shavings are a fairly common occurrence with a Kahr when new, the slide rides on the metal rails that are inserted into the frame. The plastic rails really act as a guide more than anything..........your ok !!

This thread drew my attention so I I'd like to get everyone's opinion on this photo. I just bought this pistol new and noticed this notch in the guide rail. Also, does the widening of the frame seem odd ? Feedback please. image.jpg

The plastic is obviously some out of shape..........I looked at my cw380 and it has a little of that........but the slide rides on the metal inserts, and from the picture they appear to be even across.............if the slide racks smoothly without binding, it will be very tight right now..........you should be ok......I don't have a larger poly frame kahr to look at......
What do you think Toney, Lefty, Bobber..?

The notch is supposed to be there!

The shape of the plastic is normal, some just appear "fatter" than others. As long as the metal rails are parallel and the slide does not bind up, you are good to go.

Shoot the crap out of it, all is well! :getdown:

Sometimes during break in you can get a bunch of plastic shavings. Just clean them out and carry on. That will quit during the break in. I believe that the shavings are mentioned in the owners manual. Of course I could just be dreaming!

Mine looks pretty much like yours. I've not had any trouble with it. It shoots just fine. Welcome
