Blue Rose's dual firing feature

Ha ha! Two barrels?! Really two rounds at a time ?! - meanwhile, Nico admired, twirling the Blue Rose in her hands.

The Blue Rose is a six-shot revolver converted from stock. During the flight of engineering thought, there was no trace of the original
form: Nero replaced the usual barrel with a new one, with two muzzlse, and now it was possible to
send two bullets at a time. Well, almost. Almost - because the striker hit the cartridges with a small lag - the trunks were located one above the other. But this small lag of a few milliseconds was the main feature of the Blue Rose.

“I see ... Two different bullets,” Nico realized. She had already pulled out the drum and examined its filling. “You somehow understood everything too quickly,” Nero remarked, but didn't get angry.

The Blue Rose was really stuffed with two types of bullets - all as Nico said. The first is an explosive cartridge that breaks the demons' hard armor, and an instant later a piercing bullet flies into the same place, which flashes the damaged skin of the enemy without any problems and causes real damage.
