*Bayonet – Can attach a short sword to this weapon, and it can then be used in melee with short sword properties. It obviously remains a two handed weapon though, not an offhand.
Rogues can treat Firearms as Crossbows for the purpose of rogue attack powers, sneak attacks, rogue weapon talent, etc.
Unless a class can use all military ranged weapons, they do not have profficiency with any kind of firearm.
