The Beretta M9 platform is one of the true classics of the handgun world and the M9A3 brings it up to date. This CO2 replica matches the original in looks, feel and weight. The slide blows back and it field strips just like the real thing. In fact, the only real difference is the selector switch that lets you go from semi to fully automatic! Blast through 18 bbs with a single pull of the trigger! This is a gun that will put a smile on your face every time you shoot it.
