Tokyo Marui USP Full Size Gas Blowback Pistol in Black

The Tokyo Marui USP Full Size GBB Pistol is a faithful recreation of the German-made USP Variant 1, offering a balance of functional realism and Tokyo Marui’s renowned engineering. If you’re after a sidearm with serious presence, reliable gas performance, and true-to-life mechanics, this airsoft pistol ticks every box. Whether it’s for tactical gameplay, training, or just as a collector’s piece, this modern classic delivers in spades.

Externally, the pistol mirrors the real steel USP in dimensions and detailing. It’s built with a rugged polymer lower frame—like its real counterpart—for durability and weight savings, and features a separate metal outer barrel and slide internals. The grip texture is sharp and grippy, while the oversized trigger guard is perfect for gloved users. The ambidextrous magazine release is positioned just like the original, making reloads intuitive for both left- and right-handed players.

Internally, this pistol boasts Tokyo Marui’s 15mm large-bore gas cylinder, providing sharp blowback and consistent cycling. It fires at approximately 270 FPS with 0.20g BBs using 144a or green gas, making it ideal for both indoor CQB and outdoor sidearm engagements. The blowback isn’t just for show—it’s snappy, crisp, and adds a layer of immersion that really elevates the shooting experience.

The USP’s action is fully functional and true to the original. It supports double-action and single-action trigger modes, with a working decocker and safety lever on the left side of the frame. Want to carry it cocked and locked or decock the hammer safely before holstering? No problem. These features make the USP one of the few airsoft pistols that mirrors real-world handgun handling so closely.

One of the clever inclusions is the 20mm Picatinny rail adapter that attaches to the proprietary HK-style rail under the barrel. While the USP frame itself won’t fit standard accessories out of the box, this adapter solves that instantly—no need for obscure HK-specific lights or lasers. It's a thoughtful bonus that adds real-world versatility without spoiling the pistol’s classic lines.

The included 25-round metal gas magazine is cold-resistant and well built, feeding smoothly even in cooler conditions. Just be aware that this model is not compatible with USP Compact mags—the full-size USP uses its own unique magazine, designed to match the scale and performance of the larger frame. Thanks to the adjustable hop-up system, this sidearm is more than capable of putting rounds on target at 20–30 meters, depending on BB weight and conditions.

Whether you're adding it to a tactical loadout or simply want a pistol with refined function and a clean aesthetic, the Tokyo Marui USP Full Size GBB offers excellent value. From the distinctive clunk of the decocking lever to the reliability of its internals, this pistol is a brilliant example of Marui’s mastery in combining realism with airsoft practicality.
