Recoil is how much the gun kicks up, it has nothing to do with the pellet spread of each shot. The only shotguns that have enough recoil and fire fast enough to benefit from a grip are the Striker and Ranger, the latter of which can't even have a grip. The SPAS's recoil resets completely before the next shot can be fired, and the other shotguns have effectively 0 recoil.
