    So my buddy with a m&p9c left his gun in a lock box under his seat for a week or 2. (yes I told him not to leave it in his car). His car has a small water leak somewhere so it is always "moist" inside for lack of a better word. so he takes his gun out today and its rusty as hell.

    So whats the best way to clean it up?

    If it don't clean up, he can send it back to S&W for refinishing. It has a lifetime warranty and they are good about honoring it. Don't ask how I know, just trust me on it.

    That's a pretty common problem with M&Ps around here. The melonite finish isnt nearly as corrosion resistant as one would think. He is already doing the only thing he can, short of sending it in.

    Rust is just orange character marks.

    Two out of the four M&Ps I've owned rusted within the first couple months of carrying it. S&W swapped out the slide extremely quickly and at no cost to me.

    I leave my M&P in my car every night; no rust in 4 years.

    Of course this is AZ with 15% humidity...

    Isn't the MP made of stainless? I understand that stainless can rust too, but isn't it generally more resistant? Is the finish they use really that bad that it negates the advantages of the metal they use? (If I am wrong, please correct me, but I could swear I have seen/heard that one of the MPs stregnths was the type of metal the slide was made of)

    Stainless used in guns and knives has a fair amount of carbon in it. It will still rust pretty good if allowed to. The ones I've seen have all started rusting around the rear sight. It appears that the sight rusts and then it spreads.

    well i told him he could send it off to S&W to get it refinished but i think he just plans on using some elbow grease and getting it done himself. what i worry about is the internals. he is scared to detail strip the gun. ive never owned an M&P; how hard are they to detail strip?

    It's a few more steps than a Glock but not terrible. Definitely doable. One thing that will come in handy is a roll pin punch. There should be some videos on you tube that show you how.

    I'd call S&W and see what they have to say. Why not?

    There was a time when they supposedly received a batch (or more) of slides that had been treated by their Melonite vendor that exhibited rusting problems. Treating stainless steel with molten salt bath ferritic nitrocarburizing requires a certain variation of the process in order not to compromise the inherent corrosion resistance properties of the stainless alloy. It's the QP (Quench/Polish) version, instead of the QPQ version, as I recall. Also, the heat used in the process must be maintained within a specific temperature range, as well.

    S&W was replacing some slides for their customers if they received one which exhibited unexpected rusting (even when carefully and properly cared for). Why not see if they'll look at this one?

    FWIW, both of my own M&P's ('08 & '09 production) have been exposed to nasty rain (including pouring water out of magazines during rainy shooting sessions, after loading them with ammo from a rain-sodden pocket while standing in the heavy rain), and I store one of them inside a leather holster in my safe.

    I wipe them off after wet range sessions, and I've even field-stripped and cleaned them after exposure to really heavy rain (but not always, if I'm not going to be carrying them before use at another range session soon :whistling: ). I've not had any sign of any sort of oxidation on either (or on the magazines).

    Mine must've received the intended Melonite treatment under optimal conditions, I guess. :)
