I am seeking enlightenment from those of you who have .44 Special conversions on M27's or M28's. I am in the middle of a .44 special conversion on a beater Model 28. It's been aftermarket nickelled to include the complete rear sight assembly. Barrel slightly overpolished around front sight but I have a spare M28 barrel and a couple of .44 special cylinders. I got into it very cheaply so I'm not going to put an exhorbitant amount into the completed project. I can do all the work (de-nickeling,reblue, grips, fitting) with the exception of the rebore. My main concern is the wall thickness of the M28 barrel after reboring to .44 and how to remark the caliber without reducing the wall thickness even further by removing the original caliber markings. Will the barrel wall be too thin after reboring? Will welding the old caliber markings full(protecting the bore with anti scale compound) and draw filing the excess give problems in the rebore process? Or should I just keep looking for a 4" M24 barrel? S&W does list a 6 or 6 1/2" barrel as repair parts, but no 4" which is what I want.
