not a lot of gun experience... have a mosberg 12/20, just got a rough rider 22lr, but the one piece I have and really love is my deceased grandfather's colt army 38 special... unfortunately, I let a guy at the range play w. it and he apparently used too big a load because he blew off the sight and blew open the barrel... so I have a couple of questions: would a barrel from a later series work? (this is the early 1900 marked series) and if not, is there a general consensus on how / if to repair it? I found a companu that would shave down the barrel to 4.5" but that seems like a last resort... any thought? I am even considering buying another whole gun just to swap out the parts!
