I own a Kimber Ultra CDp II. The shorter barrel kimbers are supposedly the ones with all the problems and should be avoided like the plague. Mine has functioned flawlessly with the factory mag as well as Wilson officer's mags. The gun is a dream to shoot and wonderful self defense weapon. I'd love to own the middle child of this like, the Pro CDP II, eventually as well. Kimber makes an outstanding product. I wouldn't hesitate to buy another.
