Still have a Remington 20 gauge model 48, wonderful light kicking gun. Bought a Remington 11-48 12 gauge, same gun, different gauge. Kicked like h*ll! Gave it to my marine son. Both are non-gas, or inertia as I guess you call them. The 12 gauge seemed to have a double kick, an initial recoil impulse and then
another slam immediately after the initial recoil. I've got 12 gauge pumps, Ithaca featherweight 37 12 gauge plastic buttplate, for example, that kicks less than the 12 gauge 11-48. Always wondered if that heavy bolt slamming back in the 11-48 contributed to the sense in increased recoil.
