I had a 6 inch 28-2 converted to 45 Colt in the late 70s. The barrel bore was bad and I picked it up for $140.00 at a gunshow. I took the barrel and cylinder off and sent it (I think) to a gunsmith in Bear, Delaware that advertised an $80.00 conversion to your own parts. He bored the cylinder and barrel and all I had to do was screw the barrel on and reinstall the cylinder. It was a beast to shoot with the pencil .357 barrel. It was accurate but the pistol was too light to shoot comfortably. When Smith & Wesson started to produce 25-5s I bought one and sold off the conversion.
