It is my 3rd 6” 1911, and it is a nice one too. Unfortunately it didn’t start out too nice. The thumb safety, as it arrived, was almost unusable. The casting (assuming it was MIM) was severely out of shape. It looked bent. It barely engaged the notch in the slide. See the pictures. It was wearing the factory stocks at that point. Kimber sent me another safety when I told them that I had fit several of them in the past. But it was another sub par part. I bought and fitted a Wilson Combat safety and it has been flawless. The trigger pull was pretty high for a “Target” gun, which is the model designation. It was gritty and was over 6 1/2 lbs. I polished the trigger bow, mating surfaces of the disconnector and installed a Cylinder and Slide “light” sear spring. It is very clean and crisp and breaks at 3.5 lbs! 
The pictures are a bit crappy, as I had to take pictures of the pictures on my PC. I emailed the original to myself, but they were very blurry when uploaded from my iPad. They don’t look much better now. And Mark, somehow I uploaded one of them twice. I don’t know how to delete the duplicate.
