A look at the Smith & Wesson M&P R8 8-Shot CO2 revolver made by KWC in this video by KWC... "The new M&P R8Co2 Airsoft Revolver is a fully licensed Smith & Wesson replica that is perfect for training and MIL-SIM purposes. Players can quickly and easily adjust firing modes mid game by cocking back the slide and alternating the switch on the opposite side of the rear sight.

Constructed with a rugged nylon polymer frame and full metal internals, the M&P R8 is extremely resilient to outside damage while still remaining lightweight and easily maneuverable. This replica is powered by a single 12g Co2 cartridge which is housed directly into polymer pistol grip. The non-blowback design of this M&P R8 replica is much more gas efficient, letting players fire off more shots on a single Co2 cartridge. Players can use the fixed front and rear white dot sights to accurately zero in their targets on the fly.  A 20mm picatinny rail beneath the barrel is perfect for adding your favorite laser or flashlight.

KWC gives the user the option to operate this revolver in both Single Action and Double Action Modes depending on how fast you need follow up shots. Utilize the adjustable hop-up to account for various wind speeds and BB weight, for the most accurate shot every time. If you're looking for a reliable, authentic sidearm to add to your arsenal, the KWC Smith & Wesson M&P R8 Co2 Airsoft Revolver may be the choice for you."
