Just read yourself per this idiot. http://forum.m1911.org/showthread.php?t=78337&page=1&pp=10 Just read the whole thread. But I will copy the biggest idiot statement. "O.k. first of all lets start with the basics on this one. Kimber barrels are MIM (metal injection molded) GASP!!!, as are their frames, slides and all small parts (which do occasionally have to be replaced due to failure). How do I know this you ask...well a friend of mine owns one of the leading barrel making companies in the business and he bought a kimber, "Cause it just seemed so nice Joe", and upon inspection he found it was MIM. Can't fool a custom barrel maker folks. Joe Chambers Custom 1911 Pistolsmith Member of American Pistolsmith's Guild" I tried to refute this moron but the site management has deleted or edited my posts and warned me to stop questioning Joe Chambers statements. And as anyone that knows me can tell you I have very little respect for Kimbers and am not a blind Kimber cheerleader...but this is incredible.
