Mach Sakai reviews what is called the "Perfect Maxima," a highly customized Tokyo Marui HK45 electric airsoft handgun that features a brushless motor and a pre-cocking system designed for significantly improved response over the stock model. He lists further personalized modifications, including installing a short-stroke trigger, reducing the main spring strength, and smoothing the grip for competition use.

Performance testing included measuring the muzzle velocity, rate of fire (17.9 rps), and a quiet sound profile, alongside accuracy tests like the APS Cup and Steel Challenge drills. The reviewer praised the light trigger pull and short stroke, which greatly enhanced the shooting experience, though it requires conscious effort to fully pull the trigger during rapid fire.

Overall, the Perfect Maxima is praised for its outstanding responsiveness and excellent accuracy, making it one of the best performing electric handguns available. Mach Sakai says that while it may not fully rival a finely tuned gas blowback race gun, it offers impressive capabilities for competitive shooting.
