Son is having his birthday soon. Planning on getting him his first shotgun. He already has a 22lr semi-auto (Henry survival rifle). His safety and skills warrant this decision. Have been thinking of something in 20 ga. and possibly 12 gauge if price is right. Just not sure if single shot, double barrel, or pump. Need something that is a youth model due to his small size. Has been shooting my side by side 12 gauge and does a good job although it seems to be somewhat heavy after 30 minutes or so at the range. Anyone have any suggestions as what to invest in. Going to stay away from 410. because I believe he won't be satisfied for very long and the ammo is somewhat pricey. Any suggestions from ya'll would be very much appreciated?
