Instead of buying a new gun----Why not try 2 3/4" shells. You could even go to 1 1/4 oz pheasant loads.
I've been using my Remington 870 that can only shoot 2 3/4" shells. They work just fine.

A 3" 20 GA is roughly equivalent to 2 3/4 12 GA, give or take. My son's Yute gun was a 3" 20 GA, and I can honestly say better than 80% of my shots on turkey have been ones that would have been a chip shot for my original turkey gun, my Dad's Model 12 GA Trap. I shoot lead throughout-- going on 40 years. I'd say if you want to lighten the load, go to a #4 or #6 pheasant load and be done with it.
