Jon,
The weight in these barrels is pretty significant. Also, the forend iron has a strap like a piece of railroad track. It could take some lightening pockets on the underside and not even show and drop an once or two easy. The bar of the action stout and could use some lightening pockets ala Parker or CSM 21 style. That kind of whittling is cake on a mill.
But, I just saw that new S&W 20g again in the pro-shop at the range. Nice part for a Turk gun...very nice. Very well sized reciever and nice fit & finish for a $2.3K gun.
