Manada Airsoft finds good improvement with the CYMA CM131s AEP that he explains in this review. The Cyma AEP pistol CM131S is the upgraded successor to the renowned CM030, boasting a new gearbox with steel barrel bushings, a high-performance TM Spec. motor, and a Gen3 Mosfet. Its aluminum slide and polymer frame, combined with a realistic palm protection on the grip, enhance its authentic appearance. The CNC slide with cut-outs, a feature often seen on real-steel models for cooling and weight reduction, further adds to its realism. The improved gearbox and Gen.3 Mosfet allow for increased battery usage and durability, while maintaining partial compatibility with CM030 components.
