I own a Kimber Eclypse Pro 2. I love it now but I have to say it was junk out of the box. Since using quality mags and installing a proper recoil spring from Wolf springs it now shoots the way it should have right from Kimber. The absolute best mags for my Kimber are the Cobra mags from Tripp Research followed closely by the ones made by Wolf springs. It's frustrating to spend a grand on a 1911 only to have to make mods(albeit simple ones) to make it reliable.
