Just at US$79.00 at RedWolf Airsoft... "A replica of the Smith & Wesson Sigma, the KWC SW40F is a functioning slide gas blowback pistol running on CO2 capsules. With a polymer frame and metal slide, the rear of the slide even reports the internal hammer to be cocked or not due to the small hole allowing line of sight to the rear of the hammer, functioning as an indicator.

Shooting in nice clean lines, it clocks in at around 390fps with fantastic kick and sound and feeding from a 26 round magazine it makes for a pretty scary choice for a sidearm. With a single-action only trigger the weapon must be cocked to make shooting possible. There is a safety tab positioned on the bottom of the grip, slightly odd but it does allow a safe state while in transport to greatly reduce the chance of accidental discharge."
