My M&P rusted on me.

zahc · May 26, 2007, 01:09 AM

With the new summer heat, my daily carry M&P9c started rusting. First on the end of the recoil spring guide, which I cleaned up, and now on the takedown lever, which won't come off. I clean it at least a couple times a week because I have to take it apart to clean all the pizza flour out of it from work. It rusted in the space of a couple days.

Oh well.

Geno · May 26, 2007, 01:13 AM

Please post some pictures. I had this problem last summer with my G17. That was a shocker. I never expected a Glock to rust.

I ask for pics because I was just PROMISED, sworn to by the firearms dealer that the M&P can not rust...impossibility! I had stopped to see the G26, and they just would not shut up about the M&P. I finally walked out.

Odd...have you contacted S&W?

Could you post pics?

zahc · May 26, 2007, 01:19 AM

pics will come in time. patience my dears.

gudel · May 26, 2007, 01:21 AM

I thought these things are melonited, supposedly hard and pretty much rustproof.
I guess melonite is not as good as tenifer.

piranha45 · May 26, 2007, 01:37 AM

I've read on some melonite vs tennifer thread that the two are made with similar but not identical chemicals, cuz tennifer can't be made in the US due to its chemicals, but melonite IS produced in the US.

mdao · May 26, 2007, 02:07 AM

The small parts are rusting, not the barrel and slide. Those are the stainless steel, treated, and coated parts. I'd think you'd have to neglect it pretty bad to get the barrel and slide on an M&P to rust.

Even Glock small parts rust.

zahc · May 26, 2007, 02:10 AM

Upon closer inspection the slide is also showing a bit of rust. Just a widdle spot, near the bore.

AZGlock13 · May 26, 2007, 02:13 AM

My guess is S&W only Melonite treats the bare slide and the barrel only. Parts like the take-down lever, slide stop, guide rod, etc. are not treated. I could be wrong though. Is the actual slide and/or barrel itself showing any signs of rust (I sure hope not)? If you find out from S&W that the other gun parts besides the slide and the barrel are not Melonite treated as well, I would talk with Robar in AZ and see what they would charge you to NP3 the parts (that would do the job on stopping the rust on those parts).

Just read your last update. Wow, the actual slide is showing some rust. Yep, get S&W on the phone as soon as you can and explain what is happening, maybe you got a M&P that slipped through the cracks and missed out on getting the Melonite treatment process somehow. Strange.

Tecolote · May 26, 2007, 02:40 AM

zahc,

Did you use CLP?

mdao,

What's the story with that Glock? FWIW Glock doesn't use any stainless parts, they treat the steel slide and barrel with Tenifer.

GotGlock · May 26, 2007, 02:45 AM

Thats the torture test glock and it sat encrusted in rock salt and water for a week to get like that.

DMiculek · May 26, 2007, 02:46 AM

The slide stop/release is not finished in Melonite.
The Melonite process can supposedly cause brittleness in thin parts.

The Glock picture is from a torture test where it sat in salt water for a while. I posted it just to illustrate that any untreated steel part can rust.

Now if the slide is rusting and it's not just dust from the recoil rod... Wow. I'd call S&W.

Geno · May 26, 2007, 05:44 PM

The rust made that pretty little Glock almost as ugly as Ramblin' Rosie!

Re: the Tenifer finish on Glocks, Tenifer is not the black finish. The black finish is a coating, a whole different matter. According to Glock, Tenifer is a metal treatment of the steel that goes very deep into it, and is extremely hard. In fact, Tenifer is almost as-hard-as hard-chrome. But, Tenifer if not the black finish that can rub off.

mdao: That link is awesome. Even my wife, who is just so-so about firearms thought that was great!

Melonite is Tenifer under a different trade name, same process. It's rare, but some peoples sweat has the right chemistry to rust even a Glock.

Plink · May 26, 2007, 06:19 PM

You might try using CorrosionX on it from now on. It ended rust problems on my guns and knives and they don't have nearly as corrosion resistant of finish as melonite or tennifer. Even stainless can rust, so it's wise to use rust protection, even on things that are highly rust resistant.

zahc · May 26, 2007, 07:49 PM

Getting pictures that do the rust justice is proving impossible with my meager equipment and skills. Basically the takedown lever has a nice dust of rust all over it and the front of the slide, kind of right where the muzzle taper ends (where it would get shiny from holster wear if it were old enough) has some dark spotty rust on it.

I'm not really upset. I never put oil on it to try to prevent rust; I hate my guns being oily. I pretty much just grease the slide rails.

Quiet · May 26, 2007, 07:53 PM

Pics or it didn't happen.

Geno · June 2, 2007, 07:42 PM

I finally had the opportunity to get some pics of my G17 that rusted. I too would like to see pics of that S&W. The salesmen claimed that the S&W pistols are very nearly rust-proof. Anyhow, here is the G17 that rusted. It looks pretty mild now after having been cleaned up. Last year, when it first happened, it was pretty ugly!

Arch · June 5, 2007, 10:45 AM

possum, some of us have acid hands

Geno · June 6, 2007, 12:49 AM

None of my other Glocks are rusted. I suspect that it is just something wrong with this one's finish.

zahc · June 25, 2007, 03:42 PM

new camera technology made possible by my sister.

It's rusting in the slide serrations now. I should have included the 'Stainless Steel' rollmark in one of the photos.

cbsbyte · June 25, 2007, 03:49 PM

Any gun can rust, they are made out of metal. But this is a little much for a new model with a "tough" finish. It looks like the finish is not properly applied to the metal. Not a good sign. Hopefully it is just one batch and not a serious flaw in the MP line.

tydephan · June 25, 2007, 05:52 PM

Zahc,

Have you made a call to Smith about it? I'd be curious as to their response.

Thanks for posting the pictures.
