Greetings. Giving some thought to making the switch from a Gen 4 Glock 22 to the M&P .40. I really like the way it feels/ looks. However, googling something like "M&P rust" shows far more hits than I was expecting, even as recently as 2011.

I know I could send back in if needed, and S&W would take care of me. Still not something that sounds like much fun, just like I wouldnt rush out and buy a Gen 4 G19 while they're having lots of erratic ejections/ stovepipes either. Of course I also know that things get blown way out of proportion on the web.

What I cant find on the topic is if S&W knows what the issue is, and have made corrections to remedy the issues? I take pretty good care of my guns, but I have no desire to treat a combat pistol like a Diva in order to keep it from rusting.

Does anyone have the real skinny on this?
