Larry Brown,
Using a sling in the Grouse woods is a might dangerous further you end up in the wrong position to quickly mount the gun to shoot also. I have a Best J.P. Sauer 16 Gauge double gun also, it was made with the swivels way back in the late 1800's, and in Germany because of the way they hunt a lot of Fur & Feather the swivels probably were used a great deal.
Doubt the vintage 16 J.P. Sauer Grouse Gun will ever have another sling on her now that she belongs to me, however I will leave the original swivels on the gun. If the J.P. was a Drilling with the rifle barrel, that might be a different situation. They are definitely real nice Turkey and Fox Guns.
