Awwww...that ain't radical. You should see the "short cylinder" model PPC revolvers. The cylinders were cut back to where they'd only accept 38 wadcutters. Then the barrels were set back to the desired B/C gap.
Do a search for "Fred Schmidt Short Cylinder Conversion." You can probably find a picture of one somewhere.
(Others probably did it too. Schmidt happened to live in my hometown of Mechanicsville, Va., so I knew of his work.)
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
