This GBB pistol looks like a sci-fi show prop which is based on a present world weapon. Mach Sakai tries it if it still is a Glock-like GBB pistol. The CSI/Poseidon XO P-1 BK GBB pistol is a unique and airsoft gun that features a number of unique features. The slide has been boldly cut, making the front area independent, and the front and rear sights have been relocated to separate locations, allowing for stable acquisition that is not affected by blowback. It also has good expandability such as conversion to 20mm rail and support for RMR mount. Powered by POSEIDON and equipped with ORION's lower frame, it also has a semi/full switching function just like ORION.
