In this video, BB Range 042 takes a look at the long awaited Tokyo Marui P320 GBB Pistol that was finally released last year, putting an end to five years of rumours involving legal battles and production drama. Based on the civilian version rather than the military M17, this model skips the official Sig Sauer branding—presumably to keep the lawyers happy—but maintains a build quality that feels solid in the hand.

In this video, Mach Sakai compares the Tokyo Marui Hi-Capa 5.1 and the P320 gas blowback pistols during a chilly outdoor session. The Hi-Capa is noted for its smooth slide action and a high-capacity magazine that holds plenty of gas, which is helpful when the weather isn't exactly tropical. Meanwhile, the much newer Tokyo Marui P320 steps into the ring with a slightly more efficient engine, proving it can handle the cold without complaining as much as its rival.

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.

Tokyo Marui's new P320 Gas Blowback (GBB) airsoft pistol is based on the SIG Sauer M17/M18 platform, is already in the market since late 2025. Early reviews characterize the pistol's operation as having a moderate blowback action. However, Golo Airsoft issued a significant caution regarding the slide, noting that it is only slightly over 1mm thick. This raises durability concerns for owners who might consider high-power customization for the new release.

Quick summary:

Mach Sakai does a head-to-head comparison of the LayLax SIG M17 (CO2) and the Tokyo Marui P320 (traditional gas). Key physical differences he points out are the M17 having more extensive and realistic external markings, while the magazines are not interchangeable between the two models, and the M17's slide is heavier to rack.

Ahjae TV reviews the Tokyo Marui Sig P320 Gas Blowback (GBB) handgun, a full-size replica of the firearm that inspired the US military's M17/M18 sidearm. The most notable feature of this model is the incorporation of a detachable Fire Control Unit (FCU), which is modular and engraved with a unique serial number, faithfully mirroring the real steel version. Internally, the design uses an under-hammer system to optimize space and includes a large 15mm piston, which contributes to its performance and efficiency.

Mach Sakai compares the performance of the Tokyo Marui gas blowback airsoft guns, the P320 and the Glock 17 Gen5, focusing on muzzle velocity, recoil, and shooting accuracy. Using 0.2g BBs, measurements showed that the Glock 17 Gen5 had a slightly faster muzzle velocity and stronger recoil (a peak of 5.8 compared to the P320's peak of 4.3). Subjectively, the P320 offered a very smooth slide movement and a straight kick, while the Glock was described as sharper with a shorter recoil recovery time.
