Interesting discussion.

Were I marching to battle, I might value a sling.

What is the point of discussions about balance and weight and handling if you're just going to put a strap on the thing and louse that all up?

It seems especially incongruous on a side by side gun... a repeating duck gun? Maybe, but only if forced to by the trudge to the blind when the damn thing comes off immediately.

As you wish. I wouldn't mind sling attachment points (sans any 'swivels') on a gun that was built that way. There are one or two here and they don't cause any grief.

Admittedly, I'm more shooter than hunter.
