A strong second on honing/polishing the underside of the feed rails. Kimbers are fine actions, but the underside of feed ramps are not sufficiently smooth and slick from the factory. My current Montana had draggy hesitant feeding out of the box. Minimal effort with fine emery paper, perhaps 400 grit? and it's smooth and flawless. And while you're at it, smooth the chamber feed ramp.
