Hello Instructables, Today I have you my Berretta CX4 Strom. Sorry I haven't been very active lately, I've been busy helping blue mullet build the Weapon of war, also I was on vacation for 2 weeks and I started a HUGE Project. Any ways lets talk about the real Gun. The Berretta CX4 Storm is a Semi Automatic 9mm Pistol Carbine. It is a futuristic design and is used in many ways. Its great accuracy and low recoil makes it a favorite for target shooters, its reliability makes it great for the military.

Now about my CX4 Storm.

    Not building it yet, that was just to show how it attaches.
    Maybe I'll build it soon-ish, I'll have to see, but it does look pretty cool.

    dont have the pieces to build right now, just build an aug today

    So many cut pieces where is the challenge in that? Beautiful looking gun but I would highly encourage you to try building without modified pieces to up the build challenge.

    The only internal I have is of the trigger mech and the handle. Will that work?

    That is top secret my good sir, lol I probably won't be able to finish it but it's my Huge Project.

    I'm so glad that you were able build this! I absolutely love this gun. The handle looks just a little bit off, but I can ignore that, since the rest looks so epic! The sights, stock, front grip area, it looks great.

    Awesome work! You get a patch!

    Thank you so much! Glad you like it. Thank you for the patch as well! Yea the handle is a bit off, I hate the white connector handles though so I went with that.
