AIRSOFT SPRING AND CO2 AIR GUNS have been modeled to replicate some of the most recognizable firearms in the world. The Air Powered Handguns are a true representation of the original weapon. These guns are easy to operate. Pull back on the slide like you would on a real handgun and this charges the firing spring. Then, just aim and shoot. The CO2 models are even easier to operate as they don't need to be cocked (CO2 cartridge required and sold separately). The Spring Air versions must be cocked by hand before each shot. Because of the simplistic design and the low cost of AirSoft Guns, they are great for the hobbyist.
