Nineteen-lebm' and Skoal Bandits™
In my experience, I would have to vote against the 1911, and here's why:
I began shooting IDPA a few years back. There are a wealth of 1911's of every brand and price range in the club where I started. I watched every level of the 1911 compete except for IPSC race guns and when the smoke cleared, there were 500 dollar guns that jammed up, and 1500+ dollar guns that jammed up. And the kicker for me was when I was sitting watching someone clear a "house" stage and the old timer behind me said to his old timer buddy "These darn kids can go buy a glock and shoot right with my $xxxx.00 1911. " And I was shooting a sub compact Uzi Eagle in .40 that never missed a beat (which, if you listen to the hype is the biggest piece of junk ever).
I'll accept that the LAPD swat teams and the FBI and whatever other homeland "security" agency there is to throw into the mix prefers the 1911, but I am my own armorer. I don't have a dedicated guy to hand my weapon to and say, "It's having FTF issues. Fix it." the way they do.
I believe that in thousands of rounds fired trials, that quality was established. However, I also believe that if you ask an average American ex-military guy what handgun rules, he'll say "Gub'ment .45" or "nineteen'lebm" faster than you can say Skoal Bandit™. And if you ask a former Cop from Prague what is his favorite handgun, you'll get (most likely) "Czeska Zbrojovka" or CZ75 faster than you can say... something in Czech.
National pride, jingoism, call it what you will. A lot of 1911 choices are made around that idealogy, from what I've seen ("My Grandpa blew a Jap right out of his boots in Iwo Jima with one of these" or "This is what I carried in the Marines" or "If the army uses it, it's got to be good!"). And that's okay, if that's what you want. Jingoism is becoming fashionable again. Having spent time in other cultures in my life, I don't care for that sentiment in my Firearm shopping. So, I shop elsewhere in the gun cases because I feel other types are more reliable.
Not that I'm infallible either. I have a Ruger p345pr .45.
I've found the Sig Products to be very high in quality with few witnessed (by me) failures though I've never owned one, yet.
