This Beretta CX4 Storm is German made and is a true-blowback semi-auto CO2 air rifle that uses 88 gram CO2 tanks and has a 30 round removable magazine. The claimed FPS is rated at 495 for Canadian laws although I suspect it shoots well under this. It is nearly identical to it's 9mm and 40 Cal brother. It even comes in the same case. I plan to get this gun back up to the claimed 500 FPS with some minor internal spring modifications. Mine has a 3x9x40 Rubber Coated Scope, Foregrip and Bipod added to it.
