Halo 009 Spartan (Double Magnum)

DOUBLE PISTOL WHIP: Spartan can use Flurry. After any of Spartan's ranged combat actions resolve, if Spartan is within 3 squares of a character targeted during that action, place him adjacent to that character and he can use Flurry as a free action with a locked damage value of 1.

Does "any of Spartan's ranged combat actions" include grenade attacks?

Because, the ability to lob a grenade into hindering and then go double pistol whip some twerp hiding in the bushes would be more fun than a barrelful of Grodds.

THROW A GRENADE: Give the character a power action, decrease the number of grenades in your grenade pool by 1 (if greater then 0), and choose a type of grenade listed on this card. Choose a target square within 5 squares and line of fire (ignoring characters for line of fire purposes). Make a ranged combat attack targeting all characters occupying or adjacent to the target square. Deal damage to each character hit based only on the type of grenade chosen.

So, no, that is not a ranged combat action and will not work with Double Pistol Whip.

To use the Grenade trait mechanic you have to give the character a Power Action.

Well...

Thanks for the response though. Darn it.
