If you can't find it ( after downloading all waypoints from all links ), then ask again.
P.s.: I'm sure at least one of them is already waypointed.
Okay, I found aaa_aim waypoint on the web but it's not really good... So I decide to make my own version from scratch. So here you are... Happy fraggin!
(Maybe I'll also make aim_usp, of course when I have some spare time )
