my p90 is a necktie... it doesn't go anywhere when I drop it.

I generally have my serpa on my right side somewhere, either on the vest as low as I can get it or on my drop leg.

If I'm carrying my g36 the pistol setup stays the same, but I run an ms2 or convertible 2-1. If I'm ready to shoot, the sling is in 1pt over my right shoulder and under my left arm.. If I need to go hands free, I reclip to the front to change it to 2 point and pull the rilfe up under my arm so it's diagonal across my back, barrel up.

My m14 had a 3-2-1 convertible sling, I'd run it in 3 point most of the time and used the tensioner to zip it to more of a 1 point if I needed to shoot weak side.. which was extremely rare. The strap was the same, over strong shoulder, under weak arm.

generally I don't sling to my back unless I'm walking back to respawn, it's a pretty clear indicator that you're non combative at that point, or if I have to go hands free for any extended length of time. I'm not terribly concerned with speed of retrieving my rifle in that configuration, I have a pistol I can easily get to if I have to shoot. But if jumped if I don't get shot immediately, my first priority is get to cover.
