M9 CO2 Air Gun - 4.5mm

M9 pistol manufactured by KJ Works is an airsoft replica of a known Italian sidearm.  The replica was made of metal and polymer. It is characteristic for its significant weight (close to 1 kg) because it was made practically entirely full metal - metal parts include the frame, slide, magazine and the barrel. Polymer parts include only the grip panels.

The air gun is fed 4.5 mm BBs. 

Under the barrel, there is a RIS 22 mm universal rail that enables the installation of additional accessories. The rear part of the slide features a double-sided, winged selector, the slide release button is located on the right side and can be operated using a thumb. The replica is powered by a standard 12 g CO2 capsule that is located inside the magazine.

Thanks to the use of a powerful Blow-Back system it was possible to bring closer also the operation of the replica to that of the original. The system sets the slide in motion, which is pulled back after each shot and when the magazine has been emptied it stays in the rear position. This causes the “kick” effect of the replica and largely increases the sensation and the pleasure drawn from firing the replica. 

The replica comes with a 21 BB, metal magazine that also stores a CO2 capsule.

The set includes:

- replica
- hex key
