KWC KM-48HN (Model AAKCMD480AZB) — CO₂ 4.5mm Non-Blowback Pistol
Step onto the field with the KWC KM-48HN — a semi-automatic, fixed-slide sidearm built for reliable, repeatable performance. The die-cast metal slide gives the pistol an authentic weight and rugged durability while the reinforced ABS polymer frame keeps handling light and comfortable during long skirmishes. The textured ergonomic grip helps you keep control for faster follow-up shots and consistent aiming.
This pistol fires 4.5 mm steel BBs and delivers about 2.5 joules of muzzle energy — hard-hitting for close to mid-range engagements and consistent from shot to shot thanks to its non-blowback, fixed-slide design. Because the slide does not cycle, 100% of the CO₂ energy is directed to propelling the BBs, improving efficiency and consistency.
Power comes from a single disposable 12 g CO₂ cartridge, offering long runs of reliable shots and up to around 200 rounds per cartridge under typical conditions (actual count varies with temperature and usage). The pistol uses a 15-round drop-free magazine for fast reloads so you can get back into action quickly.
Built for both casual skirmishes and more serious training, the KM-48HN includes an integrated Picatinny-style under-rail for mounting red dots, lasers or lights — a flexible platform to customise your setup for night ops or rapid target acquisition. Routine maintenance is straightforward: swap the CO₂, clean the barrel and magazine, and you’re ready for the next match.
