Close up under the the support side armpit - usually with the muzzle canted slightly upward with a horizontal style rig.
The exact distance under the armpit will be for you to decide.
Once you wear it for a while and figure out exactly where it feels and carries best, cut the extra doggone strap leather off.
Funny...TV "boob tube cops" started wearing them way down low because Galco/Jackass always shipped their shoulder rigs with lots of extra strap leather for user adjustment.
I guess they thought that since Galco ships their shoulder rigs out with the holster & mag pouches positioned toward the end of the harness straps that was where they were supposed to stay forever & somehow it "stuck" totally asinine.
