    Great product! Added to my 1301 without any problems.
    Preform well when loading and unloading. No issues in
    operation when firing at the range. Worth the money
    to increase the amount of rounds(7+1) for home defense.


    What can I say???? You get two more shells into the fastest semi-auto shotgun on the planet. Bonus is that you don’t have to invest extra money in an aftermarket flashlight/laser railmount or swivel mount. They are included!!!

    Item was exactly as described and installed in less than 5 minutes. The construction of all parts is very robust. A very solid and very attractive improvement to my Beretta 1301 Tactical shotgun.

  4. Paul Gaddini

    Was looking around for an extension kit for my 1301 and all roads lead to MXT! Super easy to install, high-end parts, and flawless functionality! 7+1 is a game changer! Last but not least, the pic rail and swivel attachment are included! If you are reading this, stop and click the buy now button!

    Well built, easy to install and adds two rds to my 1301 tactical. Great purchase

  6. Marc

    Terrific addition to your Beretta. It also fits the 1301 Competition Pro Gen 2. I specify Gen 2 because thats’ the one I installed it on. Most likely fits Gen 1 as well.

    Factory specs
    Fits perfectly and adds two rounds to the magazine. Aluminum is a perfect choice for this platform. Beautiful design, machining and anodizing. Strong enough to run without the clamp. With a small bump in weight and bulk, I can add a QD mount and a light rail. Nothing else available comes close.
