I can't equip the pistol. I bought it, but when I try to equip it, nothing happens. I press R2 and highlight the gun, but again it won't equip. Sorry if this is a dumb question but I have tried around 50X and nothing's happening. I'm at the part of the game when you have to blow the powder keg and so I'm basically stuck until I can figure this out. Any help would be very appreciated. Thanks.
