Stan,
This should give you an idea how it works.
When the hoop is formed it is not a pure half-moon shape, rather, it has a recess that allows some clearance for the leather sling itself. The sling in the first picture has not been fitted to a gun just yet, the second photo shows an old sling I have here at the place. The strap itself is what tensions the unit to the barrels, and as time goes by, it actually shapes itself to the individual gun, which allows for some movement back and forth. I prefer that to a fixed swivel as the guns weight can be more comfortably distributed when wearing different clothing, or actually carrying something in my hands, and having the gun slung as well. I don't even notice the sling when I'm shooting, because the top of the hoop isn't near the rib of the gun. The sling on my R10 has a buckle in the middle, which, allows for a bit more adjustment. If I were as fat as jOe is (did you ever see the picture he put up of himself, since removed, 525 lbs, minimum) I would let it out to the maximum, but, I use it at a tighter setting.
Anyone who bad mouths it, without having tried one, is pretty dense. They work very well. The bad news is, I did just hear from Geoffroy today, and he is sold out.
Best,
Ted
