This is again just proof that “people” can screw up perfectly good guns.Here's an interesting read about corrosion on a Glock and an alloy-framed Sig. Note, I'm not saying this WILL happen, nor do I have a thing against alloy-framed guns...I own a bunch of them, and carry one regularly.
The guns in this article were clearly neglected and stored improperly. That's not something I would ever willingly allow to happen to any firearm that I own, but sometimes things happen that are out of our control. An extended trip in the backcountry can expose a handgun to all kinds of stuff, or spending a lot of time near harsh chemicals or saltwater. Sweat will do it, too. Polymer fares better in those conditions.
In my own personal experience, I've had several guns rust during daily use and with regular maintenance. I have yet to blow one up, be it steel, alloy, or polymer-framed.
