Id go springfield, those guys at IMBEL in Brazil sure know how to make their guns. But I would have a SIG, Glock, or S&W 99 in 45acp well before the 1911 due to the mag capacity, high center of gravity, weight, grip safety, and internal extractor. The fact is the 1911 is an Edwardian era design, and although popular I feel its more out of nostalgia than anything.
I disagree also. Its popular because it works. There is a reason why the 1911/2011 is the most popluar run shot in USPSA, it has an amazing trigger, points naturally and if well designed and fitted, will run 100%.
The problem with reliability is that everyone and their mother now makes a 1911 and mags there are alot of quality control problems, and since the design relies heavily on the mag, you have alot of issues with out of spec mags.
I have a 1911 with an external extractor, works very well when designed correctly...ie S&W Not Kimber. I have a 2011 with an internal extractor (an Aftec) works awesome.
The 1911 has 35K rounds thru it with the only malfunctions being reloading mistakes or dirty mags.
the 2011 has run 10K with the only failure being reload mistake, dirty mags and mag lips out of spec
