This has come up in a couple of other threads, so I thought I'd make a new one, instead of threadjacking other people's threads. Here's my question. How do I properly store my guns? I have a Colt Combat Commander, Glock 23, and S&W 642. Normally I just leave them in sitting on top of 1/2" of foam, either in their respective boxes, or in a "safe" place. My Glock's been fine with this for 1/2 a year, but now that I have a nice Colt, I got to thinking about whether or not foam was the best thing for my guns to be sitting on all day... What should I be doing to avoid rust over the long-term? Is it ok if I leave one or more of my guns in a leather holster at all times? Thanks!
