100% agree. The wife has tried all my weapons and the ease of use plus the wide range of coverage led her to pick the Browning 12 gauge pump as her favorite. It was easy for her to load, point and pull the trigger. I pity the poor fool that tries to get into the house when I am gone. Double tap.Mossberg 590 in almost any of the configurations.
Cheap, will cover up both sides of a doorway and won't penerate through 6 walls killing someone else in the house or your neighbor.
Shotgun = best close range weapon in the world.
Oh and he won't need to spend a lot of time at the range to put some 00 or 4 buck in some assholes chest.
If he thinks the 12 with 3" shells is too much get him the 20 gauge.
