I think you're right, Alf. He really doesn't know why at this point. Knowing him and his situation, it's a boy toy, followed by "Let the wife shoot it", followed by Home Defense and then "Buy more guns".
I told him to consider carefully and buy what feels good to him, but don't worry it too much, 'YOU CAN'T MAKE A MISTAKE' because you'll want to buy another one anyway.
He seemed happy with that advice.
