Alan Harton did a M28 to .44 Special conversion for me, as well as two Old Model .357 Ruger Blackhawks. The 1st BH was a 4 5/8", using a Super Blackhawk barrel. Alan had to turn down the diameter of the barrel to fit the frame. This in turn removed the Ruger "billboard".
The 2nd BH was built using a 5 1/2" Colt New Frontier barrel. I later sold this one, but I still have the shorter one.
