S&J Hardware Sling Plates
One of the ways to attach a sling plate to your shotgun is to get a sling plate which is installed between extentsion and magazine tube. There are many sling plates available, here is one from S&J Hardware:

I always recommend S&J Hardware products because they are well made.
Do these plates have any performance issues with the magazine extensions? Specifically with the thickness of them not allowing the extensions to thread in all the way?
Leaf, I didn’t have any problems with those plate during tests. Also, I know that many other shooters use such plates from GG&G or Scattergun Technologies.
I have the Scattergun vertical sling plate and the thickness does prevent the extension from screwing on all the way, but it still gets about 2 full threads on there. And if you have a barrel clamp for the extension, you’ll be good to go even if it doesn’t thread on all the way because of the sling plate. I can tell you right now that the looks of the S&J sling plate trump that of the Scattergun, I just purchased my Scattergun vertical plate and im debating on swapping it for the S&J plate simply because it looks cleaner. But S&J also has the Delrin follower…personally I think they just make everything better than Wilson does lol.
