    Perry shooter has the legalities right.

    I'm not a fan of shortening the barrel. If I was to shorten my 30" Win 1200 barrel to be even with the mag extension I would stll have a 27" barrel.

    Do be careful about shortening the barrel of a gas operated gun too much. You need some "dwell time" after the shot passes the gas ports for the system to pressurize. Look at all the different gas tube lengths for ARs, for example.

    The shortest factory 1100 barrel is the slug barrel at 21 or 22 inches. I would be reluctant to cut one any shorter.

    The legal minimum length for a shotgun is 18", measured with a rod down the barrel to the breechface. No legal notification required... yet.

    Some of us Bubba's do good work, some not so much.

    There are at least two different extensions lengths. Looks funny if the mag is longer than the bbl.

    You should add some kind of front sight and some kind of choke would be nice (screw in choke tubes would my preference). True cylinder bore is not all that useful.

    Likely cheaper to find an extra factory short bbl.

    I converted my 1100 into a defense gun by replacing the bird barrel with a 21" slug barrel, changing the sight to dayglo rifle sights and adding a 3 shot extension. It is fully reliable with slug and buckshot, BUT it is NOT reliable with low-base rounds. I believe this is due to the needed gas-port dwell time that Hawk is talking about. I used a Speed-Feed pistol grip butt stock and forearm with the extra round recesses in the butt. The extended magazine tube is an ideal place for the light to clamp to with the spiral cord fed between the tube and the barrel and the momentary switch on the forearm.

    I would keep the original barrel. If you ever have regrets and want

    to bring it back to it's original configuration you can do it. New

    barrels sell for way over 2 bills. Buy a used barrel and chop that

    down, and with a rib it's easier to add a front bead sight.

    good luck thor.

    One of the on line blogs that I viewed showed a detailed U-Tube instruction session from a guy that does many 1100 tactical conversions.
    The instructor installed a Remington Tac +2 magazine extension and cut the barrel and rib to 18" which falls exactly at the end of one of the rib mounts.
    A follow up U-Tube showed him field testing the gun and it functioned flawlessly.

    buy another barrel to cut down. that way you can still use it for other things.

    Put the extension on first, then cut the barrel. A full length barrel will probably cost you more to replace.

    My Remington 1100 Tactical is 22" and the extension tube is flush with the end of the barrel, so I say get the extension tube first to make sure you don't cut the barrel too short for fit.[;)] When cutting a barrel send the tape measure inside the barrel until it bottoms out against the bolt face, that is how the ATF /law will measure your short barrel. Do not trust an outside measurement, too easy to mess things up [V]
