Giving more debuffs to a gun is not the way to go specially with just basic attacks.

That being said, perhaps adding skills may be more viable.

Such as Pinning shot, 6m -- The archer/gunner/arbal takes careful aim at the targets leg, preforming a basic attack with a chance to immobilize for 1-3 turns.

Disabling Shot- The archer/gunner aims for the targets main arm, preforming a basic attack with a chance to render that arm useless for 1-3 turns. (Prevents use of main weapon effectively treating them as unarmed).

Head shot is already a skill.
