Yeah, those nylon ones with the plastic buckles nearly cost me a rifle scope since the nylon webbing slipped through the buckles and the gun dropped out of my hands. I ended up stapling the nylon together to keep it from happening again on that gun. I have another one and it works fine, but its not nearly the same as a good leather sling. Just make sure that you look over whatever you decide on and make sure that it isnt one of those split grain stamped out piles and you should end up with a sling that last for years. My leather one has been going from gun to gun for a few years now and is just now getting loose and comforatable.
