MGB,
The sling sold by The Wilderness is a Giles tactical sling. If you get one you need a side sling mount for the front. Scattergun Technologies makes one and others might also. When looped up, the tactical sling goes over the right shoulder (if you are right handed) and the left arm goes through the sling loop. When let go, the firearm hangs muzzle down pointing to the left. To shoulder the firearm you just bring it up, since the buttstock is hanging right next to your right shoulder. It also works fine as an ordinary carry strap and I usually use it in this mode. For home defense, the bad thing about a tactical sling is if someone grabs your firearm in close quarters, its a simple matter to pivot and twist the firearm taking you down and choking you in the process. There's an excellent thread in the AFCQC/ alternative force section with excellent comments by Harry Humphries. Search under topic "slings". Harry is an excellent firearms/CQB instructor and knows what he is talking about.
