As stated above, it will likely cost you more that just having a new comped barrel installed. You also run the risk of unforeseen problems popping up with the locking end of the barrel. If the initial turning of the barrel is not concentric, the threading not concentric,the internal threading of the comp not concentric.... those compounding errors could cause the barrel to sit in a slightly different position thus ruining what was hopefully a well fit barrel, slide, and slide stop. I think you would be time and money, and less headache, ahead to just have a new barrel installed.
