I've carried a PM9 for about a year now, with the blackened stainless slide, in a Crossbreed Minituck. Now that it's getting back into summer again, I'm sweating quite a bit while working outside, and I'm starting to get some light rust on the gun.

It started on the magazine release only, and will clean up pretty well with some scrubbing and Rem Oil, but after a couple days, it starts to come back.

Over the last few days, the rust has also started to form on the slide stop and the pin that holds the trigger in. Again, it cleans up, but it shouldn't be happening IMO.  I am wiping the gun down daily, and doing a complete cleaning every 2-3 days, so it's not a lack of maintenance.

Does anyone have a similar problem? Any suggestions/advice? I know I can get a stainless slide stop from Kahr, but what about the other parts? Durakote maybe?

I pocket carry a blackened stainless PM9 every day.  I sweat a good deal when outside and working.  I have not had any issues with rust anywhere on the gun.  I would say contact Kahr and nicely ask them to send replacement parts for the ones that have corroded.

Keep us informed on how it goes please.

According to Kahr, the black diamond finish is supposed to stand up to added punishment and tougher conditions.  It shouldn't be doing that.  I have the same gun and I got it for the durable finish but Kahr should fix it for you.

Well I don't think the slide stop and magazine release are the same finish as the black diamond slide. But I'll give Kahr a call and see what they can do.

Update: Kahr said "keeping a light layer of a quality gun oil on the firearm at all time should help to control this issue." and did not offer up any other solution.

I guess it's time to try Duracoat.
