I have two questions, just out of curiosity. As the title says, what is your favorite gas semi-auto and why? I’m thinking about getting one and would like to know what your thoughts are. Also, would there be much difference in recoil between a 12 and a 20 in the same shotgun? Obviously, if the frame/gun is the same weight, recoil would be less in the 20, but within the same gun, do some manufacturers use a smaller frame?
