Na, you're good man. I just didn't want to edit my post until I made sure you were finished shopping! Heh.
Cheshire only went for the machine pistol for it's ammo capacity for pray-n-spray/suppressive fire and no one else had grabbed it at the time, as he literally has no skill in firearms yet. The main reason he is even getting a gun is to make himself look better defended than he feels he is. The absolute best he can hope for with a gun is to default with Magic Fingers hits acting as his agility, so about 2 or 3 dice before any other modifiers. Much better to have it in the hands of somebody who can use it, I'll just switch him to one of the other guns.
