Someone told me that mounting a foreward grip onto a pump-action shotgun will make it an assault weapon.

I skimmed through the AW laws and didn't see anything on pump-action shotguns.  Am I missing something?

Onto a pump-action?

Not illegal, AFAIK...

A shotgun can be considered an AW if it is one of these:     (c) All of the following specified shotguns:
  (1) Franchi SPAS 12 and LAW 12.
  (2) Striker 12.
  (3) The Streetsweeper type S/S Inc. SS/12.

or

(6) A semiautomatic shotgun that has both of the following:
  (A) A folding or telescoping stock.
  (B) A pistol grip that protrudes conspicuously beneath the action
of the weapon, thumbhole stock, or vertical handgrip.
  (7) A semiautomatic shotgun that has the ability to accept a
detachable magazine.
  (8) Any shotgun with a revolving cylinder.

Unless your pump shotgun has a revolving cylinder, a pump shotgun is not a AW even with evil features. Also note that even a semiauto shotgun can have one of the features listed, either A or B, just not both.

So he really was full of it.  Thanks.
