went through the process when I put a sling on my international.
I like the 'Super Sling', easily adjusted, in-expensive, and made in USA. but, since the swivel on the front of the Ruger is less than the normal 1 1/4" slings' width, a little research revealed a 'super sling' in 1" width, a perfect fit. The slings are not fancy, but very functional. I got mine at Natchez Shooters Supply. Cabelas and several other outlets, all had the 1 1/4" models, only found the 1" at Natchez.
as mike7mm08 mentioned, you remove the front sling swivel that comes with the sling and use the factory sling loop. the rear one just fits the stud in the stock.
have fun: it is a great rifle, light, compact and fun to shoot.
