Miller,
Im cut from the same cloth. It is hard for me to pick up a box of either 28 or .410 ammunition, and reach for my wallet, when there is 12 and 20 gauge ammunition right next to it, for less money.
I own a .410, and a 28. Shoot either, very little. But, that 12 gauge single shot Companion 12 gauge, at about 5 lbs and small change, is a demanding little minx as well.

Best,
Ted
