I have a full size TLE/RL II with several thousand rounds through it. It's been perfect and eats whatever I give it.This includes WWB, Speer Lawman, 230g +p HST, and Gold Dots.
I have no issues with the weapon. The only holster wear I can see is slight wear at the muzzle on either side of the slide, but it's minimal.
My guns are tools, so even if it does wear, to me it's not a huge deal.
Based on my experience, I would buy another Kimber. I am looking for a 10mm Eclipse right now.
