When I read the title, I said to myself "Depends which gun fits best." When I read the posts, I said the same thing. As for the 20, the 1 1/8 ounce three-inch works great for me although 90 per cent of my shooting is with 12s. I don't fire enough shells to feel anything unpleasant, almost religiously picking up my tollers at 8-8:30 a.m. and going to other things. I hunt nearly every day.
