I've had an Ultra Carry II in Stainless and an Ultra CDP II. Both were excellent guns, with no issues, right out of the box. These are 3" barrel guns, so not as accurate as a 5" barrel but plenty of accurate for up close work.
That said, Kimber does use MIM parts on non-critical areas and I do not find that objectionable at all.
You'll note I said I've "had" those Kimbers, and, alas, I sold them once I discovered the R9. After all, the best gun is the one you have with you when you need it. The R9 allows me to "have" it with me everywhere. The Kimbers did not.
I DO have one .45 though. The one I ended up keeping is a Warthog Stealth, which is a most excellent gun and highly reliable. But it mostly just sits in the safe, being lonely and all...
