My '29 Izhevsk came with the old "Dog Collar' Sling, which I find it too short even fully extended to use as I would any other sling. Is any viable replacement out there, without expensive modifications?
When I was a Dicks sporting goods they had a large selection on slings and at a reasonable price. You just have to look at them to see if they will work with the dog collars or if you have an alternative
