The search function does not like M&P as it says it's not enough letters - If a thread on this exists a little direction would be appreciated...

My one year old M&P has thousands of rounds through it (I shoot IPSC and IDPA with it). It's been flawless up to now. I noticed tonight that I have two small rust marks on the top of the slide. The gun has never seen rain and its pretty meticulously cleaned. I use a plastic fobus holster (not leather). The gun is always stored up on a slatwall wall, on steel hooks.

Anyone else noticed any rust on their M&P? I wonder if they'res a bad batch or if I just have a dud finished slide.
 
I have never run across any stainless steel with rust on it. You would have to be operating in pretty moist environments to get rust forming on stainless.
 
I keep mine inside it's plastic case, and for good measure I keep some of those dessicate packets inside the case. Everytime I find one inside a new clothing item or electronics box I keep em', you can also buy large bags of the stuff for putting inside your gun safe. Metal and humidity don't mix, keep your storage safe or box dry. And rub the gun down with a rem oil packet before storage.
 
They sell selica-gel in aluminium containers at gun stores, the re-usable ones. It has a window and when color changes to pink/purple you just heat it in oven to "recharge" and back to use. They are $7-9 a piece. I have them in my safe...
 
Thanks for the link baryon. I also found some more info last night. It does sound like there is an issue with some M&P's.
I own this thing to use it so I'm not going to pursue having S&W do anything about it unless it gets worse - it's only 2 little spots the size of a BB. I guess for now it will get a light coat of oil on the slide between matches.

As for the stainless steel rusting thing... I'm no metallurgist but I think that the stainless used in guns is not as "good" as stainless use in other applications. It has a little more carbon in it to make it easier to machine.
