KJ Works has been making Hi-Capa pistols for over a decade. At first, they were basically Tokyo Marui clones but in full metal, but later they started to make the system more robust and even allowed most of their gas airsoft lineup to be dual-powered, so players could choose to run green gas or CO2 by simply swapping the magazine. The KJ Works KP-19 is the latest iteration of KJ Works' Hi Capa airsoft pistol lineup. This is their first optics-ready Hi-Capa gas airsoft pistol, and it is also made of better materials.

The KJ KP 19 just like the other KJ Works Hi Capa pistols is full metal, but the KP-19 has a CNC aluminum outer barrel paired with a CNC aluminum compensator, removing the compensator will reveal 14mm CCW threads on the outer barrel allowing for tracers, suppressors and other muzzle devices to be mounted, speaking of mounting accessories, the KP-19 also features Picatinny accessories rails for all your accessory needs, like flashlights, lasers, and any other accessories as long as it is Picatinny compatible. The KP-19 being an optics-ready gas airsoft pistol, comes with an optics plate that allows you to mount red dot optics with footprints of RMR and Docter.

The KP-19 is a dual-powered gas airsoft pistol, allowing it to run both green gas and CO2, this particular KP-19 comes with a CO2 magazine but if you wish to run green gas. simply get a KJ Works Green Gas Hi-Capa magazine.
