I do not believe this was a problem of sweat or handling. I have had many brands of stainless guns over the years and only one had a rust problem. Stainless has Chrome in the steel and as it oxidizes it creates an invisible layer of chrome oxide called ceramic. It can be breached by chemicals that destroy the layer and allow the steel underneath to rust. This happened to one of my S&W 66s I had. I had the gun for several years with no problems, I bought a cheap after market case that must have had chemicals that breached the ceramic layer.
I started to get pitting rust all over the gun. The only thing that had changed was that the gun was kept in the case. It was not moisture it was a chemical in the foam and it has been documented before that some foam is made or treated with caustic chemicals that can do this. If you carry a cheap SS fork in your waist it does not rust, nor does it rust when left in the rain for long periods of time. I would say that the Melonite finish should set an even higher level of protection.
This said, it is more likely that the finish itself is causing some reaction with the stainless. I have an M&P that is about a year old and it has no problem. I would say that the individual has done something to this gun to make it rust but there are several reports on line that lead me to think it is more likely that its in the finish itself. I do not buy for one second the sweat idea. Even is left in salt water quality stainless should not rust.
