Colt 1991A1 Series-80 actually, but who's counting, right? She's been in my service for over a decade now and I have yet to jam or pinch a shell, even with hi-cap 15rnd mags/bulk ammo; she's fuckin' mint! I keep my shit clean/oiled though and run a series of small mods (comp-trigger, shock-buffer, custom hammer, etc) which keeps her working reliably.
Sad you've had issues with the 1911 platform. I've really only heard people complain about the cheap knock-offs (Rock Island, EAA, Llama, etc). Next time try shooting a Colt, S&W, or Remington 1911 firearm and know the joy I feel every time I commit homicide or celebrate Cinco de Mayo.
...isn't the 1911 platform going on 108yrs of US military service now? Why would you put an unreliable weapon on a $150,000 investment wearing $25,000 in costly gear? Sidearm or not, soldiers tend to demand working/reliable weapons and for some MAGICAL reason they return to the 1911 platform.
