The one for sale has 26” barrels. A real tough sell these days. I would just rework the wood you have and shoot it. Having a fore end made is going to cost just as much as having a new butt stock made. Not cheap and just as much labor involved. If you decide to just alter what you have your cost should be much less. You are looking to make this a shooter more than just another safe queen. But what ever you do I would not shoot too many of those 3” bombs in that gun. The kick is real.
A well placed 7/8 ounce in a full choke barrel will kill just a much as a 12 gauge. Just smaller margin of error. I shoot a lot of game with 1/2ounce and as long as I range limit myself kill just as much or more than 12 gauges shooting with me. 7/8 or 1 ounce loads will do whatever you want. Just fix the gun to your needs.
