Tokyo Marui P320 GBB airsoft pistol with new standards

Do you feel that GBB blowback pistols have not progressed much over the last decade and performance has stagnated? If so, Tokyo Marui has listened and decided to upgrade long-established gas pistol mechanisms. The TM P320 Full Size introduces a fully functional removable Fire Control Unit (FCU), just like the real counterpart. Collectors and MilSim players will appreciate the realistic field strip identical to the real firearm and the redesigned Under-Hammer trigger system located inside the trigger mechanism. Power output and efficient gas consumption are ensured by an enlarged 15 mm piston with Rail-Engine construction, meaning the piston is guided by rails to prevent misalignment, which could otherwise cause power loss or poor accuracy. About the precision workmanship typical for Tokyo Marui there is hardly anything to add, as Tokyo Marui is simply synonymous with airsoft. Right out of the box the pistol feels balanced, the ambidextrous controls are intuitive, and the overall performance ranks among the very best GBB pistols. The new hammer design does not allow the use of WE or SigAir M17 / M18 magazines, but since ANAREUS is a long-term direct partner of Tokyo Marui in Europe, we stock both spare short 26 BBs magazines and extended 32 BBs magazines. The pistol has a polymer non-slip frame and slide, so it is not suitable for strong gases such as Red Gas, however the latest generation of Tokyo Marui gas pistols can already handle standard Green Gas, delivering a solid muzzle velocity of 95 m/s. In warmer weather above 20 °C, we recommend using Light Gas to extend the service life of internal parts and the polymer slide.

Key features of the P320 GBB pistol

Removable Fire Control Unit (FCU)

The removable FCU mirrors the real firearm design. Field stripping is performed in the same way and each unit features its own laser-engraved serial number.

Under-Hammer system with 15 mm piston

The large piston and under-hammer layout ensure efficient gas usage, stronger recoil and stable performance. If you are looking for the latest GBB technology, this is currently among the best.

Rail-Engine piston guidance

Integrated piston rails prevent misalignment between the trigger mechanism (FCU) and the blowback unit (BBU), contributing to consistent muzzle velocity and reliable cycling.

Realistic controls

Ambidextrous manual safety, functional bolt catch and a 125° takedown lever correspond to the real P320 platform.

1:1 detailing and SIG P320 holster compatibility

Reinforced polymer slide, non-slip grip texture and a metal 26 BBs magazine complete the authentic handling experience. The pistol fits standard holsters for SIG Sauer P320.
