870 mag spring

Let me help you out on this one since I have some new springs handy.
A new Wilson Scattergun +2 round extension 870 spring has 39 coils and is 24" long.
Though I frown upon cutting springs, I'd be more inclined to cut to the amount of coils than to the length.

How did you manage to cram a 40 inch spring into your gun? Mine is 28 3/8 inches long and it was a challenge. I have closer to 70 coils, unless I am counting a coil in a different way. Regardless, the spring binds up and the gun won't feed properly. Perhaps I should just demand a new spring!
thanks,

In your 870's tube, you should be able to load 4 shells plus the amount of shells your extension will accommodate using 3" shells and still have about a half an inch of extra space.
The idea is to have as much power delivered by the spring as can fit in your tube with the shells. Extra power is welcomed. Considering the length of a spring only, will not necessarily get you there.
I would return the spring if I was guaranteed to receive a factory length spring of the correct size and not another cut down spring in return. You'll know you have the real macoy if both sides of the spring have finished factory ends.

Remington Factory Springs for their extensions are 29 inches in length when new. This is for their +2 and +3. They work properly for both. You need lots of spring with lots of shells to prevent "Shell Surge".

As far as I know, S&J uses Remington factory springs for his mag kits. Regardless, mine won't feed reliably at all with the new parts, but works fine in the original setup. The spring length is the only thing that I can think of that could cause these problems. Hopefully SFRC will just send me a new one, assuming that they have a shorter spring then 28 3/8 inches. We shall see, I'm still waiting to hear back.
Anyone else have feeding problems when they added an extension?

Sorry guys have been away for a few days.
The spring we use is a factory remington police spring.
If you are having problems with it being to much pressure, then trim 1.5 inch off the end of the spring.
This will fix your issue.
Their is no issue with cutting the spring, the whole idea of the follower is to stop the spring to tilting and binding.

so like our bayonet mount but with a rail on the side?
If so then we allready have this i nthe work , looking at chrissmass it will be ready

Actually I was thinking more of a rail that clips on like a bayonet. That way you could take it off like a bayonet when you didn't need it.
Unfortunately, basic loading tests with my 870 after cutting 1.5 inches off the spring haven't solved the spring binding issue. Although more reliable then before, the spring and follower get jammed in the new extension, with the follower being stuck where the new extension joins the mag tube.
I had to unscrew the mag extension to free it up, but when I started to unscrew it the spring released and fired the follower down the mag tube with such force that it became wedged!
Do you think that the spring is still too long, or is there a lip where the mag tube joins the new extension that may be catching the follower?

oss the sping is still to long but i,m really not sure what the issue is, we have sold 100,s of mag tubes and 1000,s of followers.
The only issues we have has is sometimes the sping being to long.
We have had no issue withthe follower at all.
So ill have to ask how were the indents in you mag tube removed and if it did not have any what gun do you have a Police or a wingmaster.
Have you tryed using the factory follower, if it still does the same thing then somthing is wrong.
Our follower is designed to fix these kind of problems no make it worse.

I have a 870 special purpose turkey, about 1993 manufacture. My first gun, bought new. The mag tube indents were professionally ground and polished out. You can't even feel where they were. Amazing job. The gun has always been 100% reliable. Seems to work fine with the S&J follower in the original 4 shot mag.
If the follower getting snagged on the lip where the mag parts join has never happened, then the spring must still be too long. It does feel tight and a bit crunchy when I load the last shell. I'll cut a bit more off.
thanks
