Thank you for all the feedback now there is a spell called reloading hands.
Is there anyway to get this as a alchemist and if so would this allow me two attacks a round instead?
This might make up a bit for the attacks being slow as for the swashbuckler argument you may be right about it being more optimized but the reason for me being gunslinger/alchemist is purely flavor based.
But I do appreciate the suggestion I might roll up a swashbuckler and keep him in case the gunslinger flops.
