My 590 SP came with a bayonet lug, for whatever reason, and I ran across an obsure note that the only forend mounted light that I liked (Surefire) didn't work with a bayonet lug in the way. I've put on a Knoxx stock for the smaller people in my family (adjustable length, more tolerable recoil) but I really want to avoid cluttering my gun with rails and stuff that snags on things, tears up your hands, or otherwise makes it more cumbersome or unbalanced, so my solution needs to be very simple. I'm not sure I'm ready to saw off that lug just yet. Are there any other options out there I should be looking into? Can someone explain how the lug interferes with the light, and if so, will it interfere with the sling as well?
