Simo GBB got a practical review and live-fire test of the highly anticipated Tokyo Marui SIG P320 Gas Blowback (GBB) airsoft pistol. His immediate and strongest impression is the pistol's impressive performance, highlighting a notably strong and satisfying recoil and slide return that feels superior to previous airsoft models. They also commend the aesthetic quality and the overall finish of the pistol.

Simo then conducts a shooting test using both the standard and a slightly longer optional magazine. The tests demonstrated good accuracy, with the pistol consistently firing straight after he made minor adjustments to their grip. The video also includes a test of the pistol's cold-weather performance, showing that the P320 maintains reliable function and a strong feel through the first two magazines in temperatures around 20-21°C.

A key feature demonstrated is the innovative hop-up adjustment system. Unlike many airsoft pistols, the P320 allows the user to adjust the hop-up via a dial accessible from the top of the slide after engaging the slide stop, eliminating the need for time-consuming full disassembly. Simo likes this convenience as a major quality-of-life improvement for users of the new model.
