The Proforce P320-M18 GBB Gas Pistol is a high-performance gas blowback replica modeled after the Sig Sauer P320 series, delivering an energy output of approximately 0.95 joules (≈310 FPS with 0.20 g BBs). Constructed with a full-metal slide finished in matte black and a reinforced polymer frame, this pistol offers authentic weight, balance, and reliable double-action/single-action trigger operation. The 4.7″ (120 mm) precision-rifled steel inner barrel paired with an adjustable rotary hop-up unit ensures consistent accuracy and tight groupings shot after shot.

Powered by green gas or propane, the blowback mechanism cycles a steel slide that reciprocates with a crisp, realistic recoil impulse. The ergonomic grip features aggressive texturing on front and back straps, providing a secure hold under rapid-fire conditions. An interchangeable backstrap system accommodates small, medium, and large hand sizes for personalized comfort. Ambidextrous controls include a reversible magazine release and a slide catch/release lever, while a manual thumb safety located on the left frame secures the pistol when not in use.

The fixed three-dot iron sights—fiber-optic front post and drift-adjustable rear notch—enable quick target acquisition in diverse lighting environments. Under the dust cover, a 20 mm Picatinny rail allows attachment of tactical accessories such as lights or lasers. The mid-cap magazine holds 15 rounds of 6 mm BBs and includes an integrated gas reservoir with a fill valve compatible with standard green gas adapters. A gas adjustment screw on the magazine basepad lets shooters fine-tune muzzle velocity to meet field limits. A high-tension follower and reinforced stainless-steel spring promote smooth BB feeding, minimizing jams during extended firing sequences.

Loading and maintenance are straightforward: retract the slide, insert BBs into the magazine chambers, fill with gas, and insert the magazine until it clicks. The slide stop locks open when empty for rapid reloads. A transfer-bar safety prevents discharge unless the trigger is fully depressed, ensuring safe handling. With an overall length of 200 mm and weight of approximately 890 g (unloaded), the Proforce P320-M18 GBB balances stability and maneuverability, making it ideal for skirmishes, competitive shooting, or training scenarios.
