Description
Classic Army PX9 (X9) AEG SMG (Polymer – With Stick Magazine – ENF010P)
The Classic Army PX9 (also known as the X9, model ENF010P) is a compact electric sub-machine gun styled on a modern 9mm SMG, with a lightweight polymer and aluminium body and a stick magazine. It is quick to handle and light to carry, making it a great primary for CQB and players who like to move fast.
Classic Army has been producing airsoft replicas for decades, and the PX9 brings its ECS electronic trigger system, a reinforced Version 2 gearbox and a quick-change spring together in a compact, affordable package. It suits newer players looking for a capable first gun and experienced players who want a nimble SMG.
Build and handling
The upper and lower receivers are nylon polymer with aluminium components, keeping the weight to around 2.5kg (5.5lb). The adjustable stock lets the overall length go from approximately 510mm to 590mm, so the PX9 stays compact in buildings while still fitting comfortably against your shoulder. An M-LOK handguard has room for a light, laser or foregrip, and ambidextrous fire controls make it comfortable for left- and right-handed shooters.
Performance and internals
Inside is a reinforced Version 2 gearbox with 9mm bearings, driven by a long-type motor. The ECS MOSFET trigger system gives a crisp trigger response and adds a programmable three- to five-round burst, motor protection and low-battery detection. A 6.03mm tight bore inner barrel and adjustable hop-up help with accuracy, and the quick-change spring system lets you swap springs without stripping the gearbox. Low-resistance wiring helps deliver power efficiently.
Power
The PX9 is rear-wired to a mini Tamiya connector, and a 7.4V small-type LiPo battery is recommended. The magazine supplied is a 120-round mid-cap stick magazine.

Compatibility
The PX9 takes compatible 9mm-style SMG magazines; please check with us before buying spares to make sure they suit this model. A small-type 7.4V LiPo with a mini Tamiya connector is recommended.
The M-LOK handguard accepts standard M-LOK accessories, and the Version 2 gearbox means replacement and upgrade parts are widely available.
Care and maintenance
Always remove the battery from the gun when it is not in use, and store and charge LiPo batteries in a fire-safe bag with a suitable smart charger. Unplugging the battery also protects the motor and wiring from accidental discharge.
Run a cleaning rod with a soft patch through the inner barrel every few games to clear dirt and residue, and adjust the hop-up to suit the weight of BB you are using. Use only clean, seamless, good quality 6mm BBs, as poor quality or dirty BBs are the most common cause of jams and damage to the hop-up rubber. Before storing the gun for a long period, fire a few shots on semi-auto with no magazine fitted to take the tension off the spring.
Who is it for?
The PX9 suits CQB and indoor players who want a light, short primary, newer players looking for a capable first AEG with an electronic trigger, and anyone who enjoys a modern SMG.
Please note: Battery and charger are not included. Use good quality seamless 6mm BBs. Always wear suitable eye and face protection and check the power limits and rules at your site before play.
