I finally bought a Compstock to tame the recoil of my 500. It arrived today and I just finished installing it. It's kind of funny / I'm kind of bummed...it seems to be a Hogue overmold stock set, that's been modified to add the recoil reduction spring system...and while there is a threaded hole for a sling mount, the instructions warn not to use it because it's in the path of the part of the stock that moves. They say you can attach a sling 1.25" forward of that one, but I wonder how much meat is there for the screw to anchor in. What other sling options are there for a 500 with a compstock? I know about the GG&G one that fits between the stock and the action...but the compstock already adds to the LOP, and I don't know that I want another .25"...and if you do that, do you end up needing a longer bolt to attach the stock to the action? The Compstock kit also came with a Hogue overmold foreend, but it doesn't appear to be compatible (at least not without some additional parts) with my recent 500.
