Mil Spec 1911
Not a race gun, not a "tuned" gun, but a regular, plain vanilla Mil Spec 1911, with the original crappy fixed sights. Springfield seems to have the one closest to the original. Looser slide to frame fit, takes McCormick ten round mags and will shoot almost totally dry, in a pinch.
If all else fails I can always club them to death with out breaking the frame and getting plastic shards in my hand.
