[Tokyo Marui] USP Gas Blowback (Released November 27, 2025)

An elite model that became the basis for tactical handguns

H&K's "USP (Universal Self-loading Pistol)" featured a lightweight polymer frame and was the first in the world to feature an under-rail as standard, and had a major influence on the style of tactical handguns that followed.
This model was originally developed for the American market, and the USP's operability is similar to that of handguns such as the Government, which are popular in the United States.

Tokyo Marui has modeled the Valiant 1, which features a combination of single and double action and a left-side control lever (with manual safety and decocking function) from among the many specification patterns available. The model has been carefully recreated down to the smallest detail, based on measurements taken from the original.

Key Features

• Large diameter cylinder

  The 15mm diameter cylinder is filled with firing and blowback gas, providing stable firing performance and powerful blowback.

• Safety and decocking system

  By operating the control lever, the hammer can be locked when fully cocked (ready to fire), and it can also be returned from full cock to half cock to prevent accidental discharge due to dropping, etc.

• Reproduce the same operation as the real thing

  You can enjoy two firing methods: single action, where you pull the slide to cock the hammer and fire, and double action, where you simply pull the trigger to cock the hammer and fire.

• Metal extractor

  The extractor on the right side of the slide is reproduced as a separate part. *This is a dummy that only replicates the appearance.

• Undermount rail included

  The under-rail integrated with the frame is a proprietary standard. By attaching the included under-mount rail, it is possible to mount a flashlight or other device compatible with the 20mm Picatinny standard.
