How the Derringer SHOULD work.

[Sundance]

I like this idea too, but isn't middle click switch which hand you are currently using??

Not trying to be impudent but I already stated that this would sacrifice this option if you have a derringer equipped. So say your have a derringer concealed, and you are holding, lets say, a fire extinguisher in the left hand. You middle click, it switches hands, you hear a ejecting sound and in the right hand which you switched to is the derringer, KABLAMO.

Another benefit to this would be having two derringers attached (which is already an option) and you have two free hands. Left hand selected-- [middle click] --> Right hand selected now with derringer in hand --> BLAM BLAM --> [middle click] --> Left hand selected with the second derringer in hand --> BLAM BLAM
