I've used this set-up on my 15 inch .44 mag Encore. My original idea was that the sling could be used as a support for shooting off-hand when hunting. I couldn't get the sling long enough for that to work (well, I could, but then the gun hung down by my knees). The forward sling attaches to the barrel. I assumed that it would mar the barrel, so I put a foil shim underneath to prevent and scratching, which did the trick, but the swivel scooted forward with each shot until after about 10 shots it was up against the front sight. For handgun, I'm not going to bother any more. The Encore is light enough that I can carry it open like a shotgun. I may use the sling again if I ever set my Encore up as a rifle, but until then it's sitting in a box unused.
