For the RO'S, upon seeing a participant with a magnet/pouch in front of the belt (Production/Carry Optics), would you automatically bump that person to Open? Or wait for that person to have a brain fart and use the magnet/pouch during the COF? In which most likely very seldom, if not, would happen because it would only be used for the make ready mag.
I know rules are rules but there is also rule 5.2.4, that states that you can access your make mag anywhere in between the hip bones as long as you don't access it during the COF. Unless the Load And Make Ready command is part of the COF.
The big real estate in front of the belt in between the magazine pouches and holster is there, why not make good use of it? much easier to access the make ready mag. it frees up a magazine pouch for a barney/extra mag that can be used during the duration of the COF.
