I didn't wade through the whole thread - just the first page - but I was thinking the same thing. "For combat" changes things, because there are guns that are specifically designed for combat and have a better track record of reliability. CC isn't really a factor when considering "for combat" - that's a whole other matter.
I'm not sure the 1911 will ever become obsolete - it's still going strong 118 years after its adoption by the US Army, so JMB must have done something right. As I type this, I know that my plans for my next firearm purchase is a 1911, for whatever that's worth.
I'd point out that John Browning also designed the 1911 in accordance with MIL-SPEC for combat.
Not to say it's better than the soldier sidearm..... no wait, I am, i real don't like sig's. Not to say 1911's are better than the double stack fnh, h&k, berretas, etc, Would more ammo help, after 120 rounds of .223, maybe in some corner cases.
