to be honest ive never seen any factory sling hooks on a 39 but havent seen alot of them,wally world used to carry slings that were made to attacth to a plain loop, my 82 model dosent have them or studs for a quick connect mike243
My 1978 39A has the standard non-detachable sling swivels that you have to thread the sling into. I much prefer the detachable type swivels so I recently found a new forend cap on eBay for little money. I plan to remove the non-detachable swivel & see if I can devise a method to attach a swivel stud in its place, then I can simply remove the swivel in the buttstock & replace it with a wood screw type stud. I'll post pix if succsssful. :roll:
I have a Brownell's Latigo sling on my 39A. I have QD swivels and that way I can remove or install it rapidly. I think that sling is easy to thread on and off the swivels. Look on Brownell's web site. They come in brown or black. I bought one of each a few years back and I like them.
