I've received my excellent sling from Noble (Thank you!). I'm now looking at ways to attach it. Movie-accuracy dictates attaching it to the stock and near the tip of the barrel but neither part looks strong enough on the G&P. I'm considering drilling and tapping a hole for a swivel stud in the rear of the Thompson, underneath the PR stock (not accurate but at least the right area) and maybe adding a reinforcing plate to the vent at the front. I'd love to know how others have done theirs.
