Hi Guys, I think it could be done, my concern would be the stress involved with pushing a rifling button thru for the new lands and grooves?? It is usually performed when the blank is full size...But, Rich is 100% correct, with all the 9mm barrels still available, it would most likely be a counter productive task... You could almost buy the blanks and make the barrels cheaper...
.. best to all, til...lat'r....GT
