Where in the world does one come up with the M21 being a light 8 ga ,or 10 ga when one of my M21 12 ga is 7 lbs 14 oz and the other is 7 lbs 7 oz (my #3 L.C. Smith comes in at 9 lbs 10 oz)? They were and are the best hardware store guns made in America.And,if too heavy,carry 6 less shells or you need to see your cardiologist.
