Reaper hit the nail on the head with 1911's.
All 1911's should built with generous tolerances. "Accuracy upgrades" tend to offend the "Gun Gods". Especially in a 1911 platform.
There are plenty of good upgrades that can be made to make the platform custom to your needs, but too many gunsmiths try to reinvent the wheel, to the overall detriment of the weapon.
This one is my Kimber Custom TLE II. Had a reliability upgrade to include polishing the feed throat and ramp, removing the firing pin block, and setting the locking lug. It is a full-length guide rod 1911, but it runs like a raped ape. The grips are Vaya con Dios, and the sights are XS Big Dots.
My daily carry is a SiG P-229 Elite, however.
