Hey everyone, I need some help figuring out what i need and where i can find a magazine extension for my Remington 1100 12 gauge shot gun. I have a 22 inch smooth bore deer slug barrel. i am looking for a magazine extension that will be flush with the end of this barrel. I would like to keep with a factory Remington but will settle for anything blued/metal. If anyone can point me in the right direction or give me some advise i would really appreciate it. my gun sort of looks like the one on the right of this page.

I mainly want it to be flush with the barrel. I don’t know how many shots i should be looking for and im getting confused.

Thanks in advance fellas

One thing everyone must remember is that these extensions are not threaded on very well. Look at the shallow threads and the low number of threads actually enagaging the extension. As such, a clamp must be used (like the factory extension) to secure it to ther barrel or else the extension is easily knocked off if banged into anything. If the extension is knocked off or knocked loose, the force of the spring will launch the extension and the shells in the tube could all fall out. This is why the factory extension has a very well engineered clamp with a groove in the extension to hold the clamp in position.

With a careful rework of a +2 Choate extention on my 870, I have managed to make it a +3 extention while still being only as long as the normally +2, took some careful triming of the spring, which I had not trimmed before at all, and modifications to the follower and plastic endplug in the extention tube. Seems to work well running snap caps thru it, have to take it to the range to see for sure though.

Kris, yes, all extensions are on 20″ barrel. Yes, I agree that factory extension doesn’t look good with the end which sticks out, but it allows to install a bayonet

Also, there is another extension which looks like the factory one but it doesn’t stick out past the end. It is made by Sage International, one of the readers of the blog sent photos and information about it:

Are these all +3s on a 20″ barrel? I don’t like how the factory extension sticks out past the end, it looks odd, but the other ones look normal.
