LL,
I also have a Kimber, but it's a Montana Stainless/Synthetic version in .300WSM. As to quality and fit and finish, the Kimbers are truly in a class above virtually all other production rifles. Granted, the reason is probably because the Kimbers are semi-production guns.
Keep in mind that, surprisingly enough, my particular Kimber had a defective bolt - go figure. I had a post about this about 2 or 3 years ago or so. I must say, customer service was lightning fast. I got a new bolt within about 10 days! Again, other than that, the quality and fit and finish are outstanding. I think that Sakos are also a cut above the rest, and probably close to Kimber, but I think that Kimbers are probably a hair higher in quality and fit and finish than the Sakos.
My favorite guns in the $1,000 price range are the Sakos and the Kimbers. When people often ask me what gun to get in this price range, I often recommend these two. Then, when people ask me which of the two to get, my advise is actually very simple: If you don't mind the extra weight, then get the Sako. If you want/need a lighter gun, then get the Kimber.
And trust me, after the barrel gets broken in, it will shoot better groups. Also, it appears that given that the Kimber barrels are so skinny, they are finiky when it comes to bullets and/or loads. In my 300WSM, I got about 1.5" groups with Federal Premium 180 Barnes TSX, but 1" groups with Federal Premium 180 Nosler Partitions. As such, try different loads because I'm certain that your Kimber should do better than 1.5"
