Hi Catfish,
I actually met the president of Tactical link at a firearms instructor conference in Washington state. He is a helluva nice guy and even let my friend use a sling during an advanced patrol rifle class. It is a normal single point sling but can be detached quickly. The sling stays on you and he has a special 4 point attachment that allows you to unclip the weapon but leave the sling on. Does this make sense?
He told us that he had sold them to everyone in the Washington State Striker Brigade and that they all loved them there in the sandbox.
Bottom line, good quality item, just too steep pricewise for a regular street cop like me. ($115) for the single point he put on my buddy's rifle for evaluation during the course we were taking. I am pretty sure though that he has less expensive ones ($60) or so I believe. Like any single point, it's tough to run with them as the front sight blade usually clangs you in the family jewels if you're not careful.
