The Taran Tactical Innovations Combat Master JW3 AEP (CM138) is an officially licensed, electric-powered airsoft pistol (AEP) manufactured by Cyma/EMG, inspired by the firearm featured in the John Wick 3 movie. It is known for its reliable performance in various weather conditions, a built-in MOSFET, and both semi-automatic and full-automatic firing modes. 
 
 
Key Features
Official Licensing: The pistol features authentic Taran Tactical Innovations (TTI) trademarks and design elements.
Durable Construction: It has a heavyweight construction with an aluminum (metal) slide and a reinforced polymer frame for a realistic feel and durability.
Reinforced Gearbox: The internal mechanism uses a reinforced metal AEP gearbox based on the Tokyo Marui system, enhanced with steel gears and ball bearings for longevity and improved performance.
Integrated MOSFET: An integrated MOSFET system enhances electrical efficiency, provides a snappier trigger response, and allows for the safe use of 7.4V LiPo batteries (in some packages; check retailer for specifics).
Firing Modes: The AEP offers both semi-automatic and fully automatic firing modes, with the selector switch located on the left side of the slide.
Adjustable Hop-up: An adjustable hop-up system allows users to control the BB trajectory for improved accuracy and range.
Ergonomics: The grip features an aggressive texture for a secure hold, and the design includes an enlarged magazine release and a flared magwell for faster reloads.
Accessory Rail: A 20mm rail on the underside allows for mounting flashlights or lasers.
Cold Weather Performance: As an AEP, it performs consistently in cold temperatures where gas blowback (GBB) pistols may experience "cool-down" issues.
