Interchangable barreled flintock
a multibarreled flintlock pistol
This appears to be a standard flintlock pistol of good workmanship. However these weapons have the quirk of being able to swap the entire barrel essembly over, in favour of a loaded barrel. This greatly decreases the reload time of the device, for as long as the user has loaded barrels.
Created by a weapon researcher off the coast of Dareton. These were given to the party to test and evaluate in battle. As these 2 pistols resulted in a blinded dragon, they could be said to be of a workable design.
