Short of one of the older Government issue models, none of the major 1911 makers would survive in any of those environments that you listed, at least not until you break it in with about 2-3,000 rounds. Take a Glock, Hk, or any of the other polymer pistols designed for a combat environment, and they will out shine the Kimbers, STIs, and Bears.
Oh really? Please explain where this has been tested and verified be a credible source.
I got rid of my Glock 21 because it wouldn't feed. The internet myth of flawless Glock reliability is only outshined by the myth that AKs never jam. The Glocks are usually good reliable handguns otherwise they wouldn't be so popular. However, their overblown reliability rep is more a product of advertising than reality.
