I bought one to make into a 357 with a model 13 barrel and a model 19 cylinder. Then I ended up with a python barrel and I was going to make a smolt. While waiting for the K frame barrel die I misplaced the python barrel so I put a 4" heavy barrel on the one I had and ordered 2 more frames. The python barrel will show up although I have turned my shop upside down. Know I put it some where safe LOL Maybe I should empty the safes.
