Tokyo Marui P320 Full Size Gas Blowback Pistol – Modular Realism Meets Modern Design
 
Decision Trigger – Is this pistol for you?
 
✔️ Shoot at will if:
you want next-gen mechanics — the removable Fire Control Unit (FCU) mimics the real platform
you value modularity — the FCU design allows future customization across frames
you want smooth performance — under-hammer system and 15mm piston deliver stable cycling
 
❌ Hold your fire if:
you want a supported ecosystem — the P320 platform is still niche compared to Hi-Capa builds
you plan heavy upgrades or internal work — the internals are harder to access and modify
you intend to run high-pressure gas long-term — polymer slide favor lower-pressure gas use
 
『Takeaway: The P320 isn’t just another Tokyo Marui pistol—it’s a platform shift. Built around modular realism and advanced internals, it offers a more authentic and modern shooting experience, but trades off upgrade simplicity and long-term ruggedness under high-stress setups.』

The Tokyo Marui P320 Full Size Gas Blowback Pistol is known for its innovative modular handgun design, allowing the platform to be configured into different sizes and calibers by changing components such as the slide, barrel, and grip module. At the core of this system is the Fire Control Unit (FCU)—a self-contained assembly that integrates key operational parts including the trigger and internal firing components.
 
This P320 Full Size gas blowback model faithfully reproduces both the external design and the modular concept of the original handgun. In addition to its authentic appearance, it features a carefully engineered internal system, including an under-hammer mechanism, to ensure reliable gas blowback performance.
 
Fire Control Unit (FCU)
The centerpiece of the P320 design is the removable FCU, which is reproduced in this airsoft version using the same removal procedure as the real firearm. A unique identification number is laser engraved on the side of the FCU, remaining clearly visible even when installed inside the frame.
 
Under-Hammer System
A large 15 mm piston is used for strong blowback performance. To maximize piston stroke within the limited internal space, the pistol adopts an under-hammer configuration, positioning the hammer beneath the piston.
 
Rail Engine System
The blowback engine features a rail mounted beneath the piston. This rail engine design prevents misalignment between the FCU and the blowback unit, ensuring efficient gas release, consistent velocity, and stable recoil action.
 
Slide and Outer Barrel Design
The pistol incorporates an outer barrel tilt-assist mechanism that helps prevent scratches on the chamber cover while ensuring smooth cycling. The slide itself is constructed from durable reinforced resin.
 
Highly Detailed Construction
Multiple external components—including the front and rear sights, extractor, extractor plunger, extractor spring guide, and slide rear cap—are reproduced as separate parts rather than molded into the slide. Even internal details that are normally hidden when assembled have been carefully recreated.
 
Realistic Lever Operation
The ambidextrous manual safety replicates the same structure as the real handgun. The takedown lever accurately reproduces the original rotation angle of 125° and includes a safety feature that prevents operation while a magazine is inserted.
 
Distinctive Grip Texture
The grip’s anti-slip pattern on the front, back, and sides is not created using conventional embossing. Instead, it is produced by laser engraving directly into the mold, delivering a sharper and more authentic texture.
 
Cold-Resistant Die-Cast Magazine
The pistol comes with a 26-round die-cast magazine designed for durability and reliable operation, even in lower temperatures.
