    What is the purpose of a rotating barrel? I read that it helps reduce muzzle flip because of the low bore axis. Anything else, because I have not shot it yet and was just curious.

    Berreta's website does not mention a rotating barrel as a feature.

    The low axis bore of the storm is designed to reduce muzzle flip, according to the information on the website.

    Beretta pioneered the rotating bolt on shotguns, everyone is copying that now. Maybe this is the next greatest thing.

    Just sayin....

    I think I heard somewhere that browning did this like a hundred years ago in there pistol. Don't quote me on that.

    if you plan on running a suppressor the px4 will unscrew the supressor and it will go flying off the end of the gun...

    they arent suppressor friendly guns.

    I did not say any rotating bolt, just on shotguns. Even the re-introduced A5 has rotating bolt, my Granddaddy's A5 did not.

    Oh man I fell in love last weekend I shot my first a5. Wow I'm in love. I'm trying to get one for myself I love the modified choke at the end of the barrel.

    The A5 is also a long recoil operated semi, so the bolt and the barrel recoil together back. They come to the end of their travel and the barrel returns forward and then the bolt closes (feeding the next round). Interesting consept but not used much anymore. I haven't seen an old manufacture Browning that uses a rotating bolt.

    The rotating barrel was introduced with the Cougar. Remember just about all semi-auto pistols in 9mm up have "locked breech" set ups. Whether it is a Browning linked system (1911) or a linkless design (just about everyone else) the barrel stays locked with the slide for a short distance as the slide moves to the rear. The barrel drops in a conventional system, unlocking and allows extraction and loading of the next round. Beretta simply locks/unlocks without the barrel dropping. THis allows the barrel to be mounted lower in the pistol. THIS is what reduces muzzle flip.

    The rotating barrel also acts like a gyroscope, to aid your balance in shooting while inebriated.

    rotating barrel

    My storm has a polymer frame, and thus lighter. So the rotating barrel dissipates some of the recoil by changing some of the linear motion into rotation, and the gun shoots soft. Love it.
