This carbine, the Beretta CX4 Storm, using std 9mm Luger ammunition - appears at first glance to be out of a Flash Gordon or Buck Rogers movie! However, let looks not deceive as ... once held and fired it is surprisingly ergonomic and good to use.
Its downside, well with this one ...... is an atrocious trigger but one that you can get used to, just! Accuracy is very good and with the red dot it makes a very handy platform. Weight is modest and so a very easy gun to tote all day if need be. It will accept mag's from other Berettas, such as the 92 series.
