RE: Recoil, I'd agree that the Benelli is a thumper, but it's hard to beat the old model Remington ll-87 semis with the reciprocating barrel. It was like trying to shoot a jackhammer. I had one I cut down (with a Poly-Choke, no less) for self-defense use back in the 1970s. Using the high powered buckshot or slugs that were available at the time, it was a toss-up wether to shoot the miscreant or just hand him the shotgun and dare him to shoot me.
Rob H.'s counterintuitive method of using the weak hand to push forward hard on the forearm while plulling the gun to the shoulder with the strong hand (sort of a reverse Weaver) takes a little sting out of a short-barreled 12 gauge. That's how I shoot my looney Serbu Super Shorty.
