So the father of a friend of mine's wife (that was a mouthful) passed away this summer and among the other things he left them was this Remington Model 31 12 guage shotgun. Neither of them having their PALs, gentleman that I am, I took it off their hands. I had never seen or heard of this model of shotgun that predates the 870 prior to this. Anyways, it shoots fine, cycles no problem and suits my needs just fine except for 2 things: there seems to be no provisions or obvious way of mounting a sling and the length of pull for me is longer than I like (it's ok for a bladed stance but I prefer to shoot more squared up). What are my otions? Will 870 accessories work with it? Is there an easy way of mounting a sling that I'm overlooking (it's mainly the front mounting point that I'm unsure of, it's easy to put an adapter that wraps around the butt stock like for a 3 point sling out back) Any and all help appreciated!
