Thanks, your less sentence was the info I needed, having never fired a recoil operated shotgun.
The 20 gauge would be for target games - skeet and sporting clays mostly, so I'd likely be firing 7/8 ounce target loads. But the 12 gauge AA "Sporting Clays" loads I recently bought use a 1 ounce load of 8's, only 1/8 oz difference.
This reinforces the thought that I'd be better off getting a replacement barrel for my 12 ga. 1100 that can use interchangeable chokes, mine came with the built in modified. It would certainly be cheaper.
Now, having said that, I honestly thank you for your advice but have to say you need to work on your enabling skills when someone is contemplating buying a new shotgun.
The correct answer is "Yes, a Benelli M2 20 gauge would only kick about 1/3 as much as your 12 ga. 1100, besides increasing your scores by 50% and probably causing you to lose some weight as well."
