Right hip pocket and clip it to your belt loop. Much comfier than the harness and it's right there when you need to search, the manual says this is the alternative to the harness. Just make sure it's not a patch-pocket and don't wear your pants supper sagging and there's pretty much no chance of them getting ripped off in a harsh slide.
The only disadvantage is when someone digs you out if they need to switch yours off and don't know where to look.
