You kidding? Shotguns had to be one of the most annoying parts of MW3. The Extended Mags glitch was super annoying, and the only shotgun that I deem to be difficult to use is the AA-12, and even then, just put Extended Mags, Scavenger and Damage on, and you basically fixed the AA-12's problems all in one.

And lest I forget the OPness of the USAS 12.
