Mach Sakai checks the Marushin Five-seveN CO2 Blowback Pistol in FDE. Fully licensed and sold under the Cybergun brand outside of Japan, this has full trademarks, ambidextrous safety, heavyweight magazine, adjustable rear sight, under rail for weapons accessories, and large magazine release. A good primary to go with this is the FN P90 as they share the same ammo.
