How was Altman shot when he was tied up?

The reason why Altman can shoot is that when shooting public scenes, special technicians or body double will wear special Altman's coat or various monster holsters. Altman is the floorboard of Japanese special heroes produced by Yuangu Co., Ltd., and the origins of Altman heroes in the works of Altman in Showa era (Altman to Eddie Altman) are all set as cosmic people in M78 nebula.
