(PSN)JadedCthulhu

Hey everyone! I've been playing a lot of Hydroid Prime and I really want to make a theme loadout for him. So far I've got the Zarr building for his primary (what pirate doesn't want a cannon!?) and th3 Destreza building for his melee. What I seem to be stuck on is a secondary weapon. My original though was Akbolto since they kinda look like flintlock pistols, though I'm wondering if there's any better. Any help would be fantastic Tenno!
