M&P Finish

[J]

Where was the firearm stored? What was the wear?

I've made the mistake of leaving some reloading press parts in the truck, and with the heat and cool each day in the winter, water condensates, and rust forms.

I have more M&Ps than I care to admit, with no signs of any such damage, I have to imagine something contributed to the rusting.

Is it just surface rust? Will a copper or brass brush take it off?

I'm curious as to what the cause could be as well. I've carried my M&P daily for 2 years with no rust issues what so ever.

Firearm has always been stored inside in my basement in a gun safe.

It appears as though earlier model M&P's are more prone to this issue.

Im not sure if it is just surface rust or not. I'm not going to attempt to repair it unless I hear that S&W won't warranty it.

If it is surface rust, it will continue to rust in that location because clearly the finish is no longer there.

Mine rusts from sweat from carrying everyday.

Today i received a fairly generic RMA E-mail from S&W to send me a prepaid shipping label...

So far it looks like no one actually ready my e-mail and just an automatic response system replied to me.

I'll provide updates as they roll in.

I have had to deal with Smith & Wesson's repair department in the past and it was a smooth transaction. I wouldn't even worry about removing the aftermarket parts. If they have to replace the slide, they will take your sights off and return them with the pistols (though most probably not installed). Same thing with the Apex trigger kit.

Corrosion issues were very common on early model M&P's. Outside of these "first gen" guns, most other pistols that I have seen suffering from corrosion are due to insufficient re-lubrication after degreasing the metal parts while cleaning.

Any idea of what serial numbers are considered first gen or early production??

My M&P is a DXU Serial.

My second slide has rusted as well, just not as much.

Gotta be something in your routine? I have MP9 that I carry once awhile.. and MP9c that she carries often. No issues here.
