Only do it if you actually dislike the gun. I nearly traded my SIG220 for a USP when I found one. Now I know that would have been a mistake. Although ten rounds, super-strength and the ability to use condition one are nice, that particular USP will never be a match for my particular 220 for accuracy or comfort. Recently I thought about trading the USP for a Kahr K9 (who needs two .45's and no 9mm's?) but I came to my senses. If I still want a Kahr when I have the cash to buy a gun outright, I'll get it then. But I'd rather wait and have the Kahr AND the USP than lose the USP for an unproven gun.
Again, though, if you were looking at trades because you dislike the Kimber for some reason, all that goes out the window.
