I have never owned one.  Im in the process of trying to talk a guy into selling me one.  I love em and havent heard any of my friends that have them say anything bad about them.  I know the one Im trying to buy, I fell in love the first time I picked it up.  That just dont happen with me.
I have heard that the older ones, the Kimber of Oregon is better than the newer Kimber of America.  
Everyone that I have seen or heard of shoot like mad.  Good guns all the way around.  If I can talk this feller out of his, Ill let you know more.  
 
You will most likely have to pay pretty good money for it, I do know that.
