I agree with these choices, but with the caveat that you need to make sure your wife can handle them, too.
That means the shotgun might be a 20 gauge instead of a 12 gauge, and the revolver might be a Ruger SP101 instead of a GP100.
The post about getting some good training is excellent advice, too.
I was in Cabelas (Hamburg PA) on Sunday (The Lords Day) and there was not one (1) single box of 00 buckshot in 20 gauge on the shelves. Quite a bit of 00 buck in high brass 12 gauge though so I had to settle.
Right before Christmas in that same store there was a full pallet of PMC 223 (REM) at the checkouts for $6.49/box. Saturday not a single round of 223 or 5.56 of any manufacturer in the entire store. I would imagine (but I’m sure someone here knows exactly) that a pallet of 223 is what, half a million rounds or more?
They did have a reasonable supply of pistols available. Mrs fatboy almost puicked up a Baretta 9 mm to add to her collection.
