I posted this on a different forum and I'm trying to get varying opinions and want to throw it at you here. For starters, I'm glad to be part of your community, thanks for having me. I recently purchased a S&W M&P 9mm std. and I'm truly thrilled with it. But here's a question I have concerning a cleaning method, and wonder if anyone's ever done this or heard of another that does this. After field stripping the pistol, submerge the polymer chassis in a mild soapy water bath and scrub the action with a nylon brush to clean it and then rinse well with fresh water. Knowing the materials involved in the chassis makeup (polymer plastics and stainless steel), I'm intrigued by the thought that this isn't necessarily a big no-no, provided you're very diligent in the drying step using compressed shop air (filtered) and leaving the pistol disassembled for a period of time for an extra measure of certainty that it is throughly dry, and then of course a good oiling/lube for the action area. Sounds nuts, but why not?? Gunsmiths, anyone? Thanks for any input.
