The M18-P320 ProForce Black GBB Pistol is a high-fidelity gas blowback replica combining the compact form of the Sig Sauer M18 with ProForce enhancements. Featuring a full-metal slide with matte black finish and a reinforced polymer frame, this pistol delivers an energy output of approximately 0.95 joules (≈310 FPS with 0.20 g BBs). The 4.7″ (120 mm) precision-rifled steel inner barrel paired with an adjustable rotary hop-up unit ensures consistent accuracy and tight groupings, whether for casual plinking or competitive skirmishes.

Powered by green gas or propane, the robust blowback system cycles a steel slide that reciprocates with a crisp, realistic recoil impulse. Ergonomic grip panels feature aggressive stippling on front and back straps, providing secure handling during rapid-fire sequences. 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 on the left frame locks down the trigger when not in use.

Fixed three-dot iron sights consist of a fiber-optic front post and a drift-adjustable rear notch, enabling quick target acquisition in varied lighting conditions. Under the dust cover, a 20 mm Picatinny rail accepts tactical accessories such as weapon lights or lasers. The mid-cap magazine holds 15 rounds of 6 mm BBs and integrates a 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 comply with field limits. A high-tension follower and reinforced stainless-steel spring promote smooth BB feeding, minimizing jams during extended firing.

Loading and maintenance are straightforward: retract the slide, insert BBs into the magazine chambers, fill with gas, and seat the magazine until it locks. The slide stop lever holds the slide open when the magazine is 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 M18-P320 ProForce Black GBB Pistol balances stability and maneuverability, making it ideal for airsoft enthusiasts, tactical training, or collectors seeking a realistic Sig Sauer replica.
