I refuse to dignify the panic buying by buying magazines I wouldn'tve bought anyway.
That said, I do have an order coming up for a 13 rounder for my CZ 75 .40, 2 12-rounders for my SIG P229 .40, and a Wilson low-profile #47 for my CBOB - but that's because it's christmas time and I've been wanting those mags for a while, not because of Obama.
I've never met a handgun I felt I needed more than 3 magazines for - and for most I'm very satisfied with two.
