    What's up with the rotating barrel?

    FOM just purchased a Beretta Storm .45 and one thing that impressed him about it was that it had a "rotating barrel".
    Thing is - he can't tell me what the rotating barrel accomplishes (better accuracy, less recoil???).

    Can someone here enlighten me on the advantage of a rotating barrel?

    The storm can be re-configured to be a lefty. I suspect this may be what he's talking about. Can't imagine it having a rotating barrel for a number of reasons. It's a rifled barrel and the rifling wouldn't work if the barrel rotated... I think he's just calling something by the wrong name. I've looked at the Storms a lot over the past year and I don't believe they do anything differently than a typical pistol action.

    Great gun with the only limitation being the lack of higher capacity mags for the .45 version. Still Iwouldn't hesitate to get one in that caliber if I could afford it!

    The rotating barrel serves the same purpose as the traditional Browning link, that is, it maintains a slide to barrel lock until the pressure decreases. The difference is that the movement is not vertical, but rather more of a circular "torque" movement that allows the barrel to stay "on target" longer. Is is supposed to help with recoil movement also, as the rotating link may be in contact longer. It also makes the whole barrel and link thinner, thus a lower bore axis. Several pistols utilize this type of system.

    It's just another way to make a gun.

    Here is an excellent article that explains the advantages and design principles behind the rotating barrel lockup.

    Excellent resource – thanks! Dang, I’m soOoo old school as I’ve been away from the hobby for a bit too long.

    Tidbit: I don’t see the US Military re-adopting the .45, as the change to 9mm was a NATO alliance agreement. But then again, my knowledge curve is still on the down stroke.

    gun-tests.com had a review of the the Storm and Cougar a while back and they raved about how accurate the rotating barrel design was. Seems like a neat concept that works.

    By rotating as the action cycles, the barrel stays on a single plane, not dropping down like the Browning design. The benefits are increased accuracy and "softer' felt recoil with less muzzle flip. My Beretta Cougar 8000D uses the same system (the Px4 series grew out of the Cougars) and it is definitley the softest shooting 9mm I've fired, and much more accurate than I am, but so are the rest of my guns.

    Thumbs up Great Gun Less Recoil

    I've owned the .40 Berrets PX4 Compact for concealed carry
    Its was nice,.. I liked the size overall it was very easy to clean and disassemble
    The rotating barrel did make staying on target better .. "Im a pretty good shot" LOL
    But I could feel the difference in recoil compared to my Glock .40

    If you don't own one id say at least try one out and see if you like it.
    And YES the barrel visibly rotates
    Pull back on the Slide and watch if you just want to see it move

    My compact .40 is very accurate. 2" groups from a sand bag rest at 25 yards by a half blind arthritic old man accurate. On top of that it is the mildest shooting .40 I have ever shot.
