Does anyone else have one of these? It is a .410 gauge made by Sporting Arms. The gun is a single shot weapon with a knob-type safety on the right side. It has an external hammer that looks like something on a lever-gun. I shot it for the first time today. This was the first time I ever fired a shotgun. I must be awfully weak because I only put 5 rounds through it and my shoulders are still sore. The recoil does not seem to jerk the gun, but seems to go straight back to the shoulder. It makes me dread firing the Remington 870.
