samehada only let's people who have more chakra then there current master wield it. there's also no way that mangetsu had more chakra then kisame or someone would have mentioned it especially since they mentioned kisame's chakra level. mangatsu and suigetsu where stated to be "boys" and they trained together when little to become members of the team.
