The P320 is a modular, semi-automatic pistol built around a removable Fire Control Unit (FCU) that houses core working parts—trigger, hammer and other operating components—allowing barrels, slides and frames to be reconfigured into different sizes and calibers.

This Full-Size configuration has now been added to our gas-blowback lineup, faithfully reproducing the look and FCU feel of the real gun while incorporating an under-hammer operating system and other performance-focused internal mechanics.

Key features

Fire Control Unit (FCU)

The FCU, the heart of the P320, is custom-designed for airsoft while remaining removable using the same procedure as the real firearm. Each FCU is laser-marked with a unique serial number on the side, visible even when the unit is assembled in the frame.

Under-hammer design

To maximize piston travel within limited internal space, this model uses an under-hammer layout that positions the hammer beneath the piston. The piston is a large-bore, 15 mm diameter unit for strong, reliable operation.

Railed engine

A railed engine is fitted to the lower part of the piston. Because the rail locks the FCU and the blowback engine into precise alignment, gas discharge efficiency is consistent and both muzzle velocity and blowback behaviour are more stable.

Slide & outer barrel

An outer-barrel tilt-assist mechanism protects the chamber cover from scuffing and ensures smooth cycling. The slide is made from reinforced resin.

Faithful exterior details

Front/rear sights, extractor, extractor plunger, extractor SP guide and slide rear cap are reproduced as separate parts from the slide. Even details that are normally hidden when the sights are assembled into the slide are reproduced.

Realistic control operation

P320’s ambidextrous manual safety is replicated with true-to-life structure. The takedown lever rotation angle is accurately reproduced (125°), and a safety feature prevents the lever from rotating when a magazine is inserted.

Distinctive grip texture

The anti-slip texture on the grip (front, back and sides) is not simple molding — it’s laser-engraved into the mold to reproduce the characteristic raised pattern with high fidelity.

Die-cast magazine

Comes with a 26-round die-cast magazine that is resistant to cold.
