I recently bulged the barrel in my limited performance center model 14 4inch revolver. I was heart broken!! i called smith and wesson and they told me because its no longer made they will not and or cannot replace my k frame 4 inch full lug barrel.... after being down in the dumps for a while i found "Mcgowen precision". after a call and a few weeks they managed to reproduce my barrel EXACTLY down to the last detail. I thought they would just get close enough but when I got it back I was just amazed at the level of craftsmanship by Mcgowen. I couldnt tell the difference between my old barrel and new one. funny enough I could only tell the difference between the two because the new one wasn't stamped "smith and wesson". not too much of an issue because the gun looks the same and im not thrilled with the service that i got from smith and wesson anyway. a horror story if you ask me. they told me "good luck finding another barrel" and left it at that.....
