Do what you want, I don't give a rats ass. They arent widely used because they start interfering with other shit, like a 40 rounder on the front of a vest covers almost the whole plate, meaning you cant have an EUD, admin pouch, grenade pouch or PTT that people would normally put in that space. Similarly, on the belt a 40 rounder is tall enough that it will start to snag on your cummerbund. Historically countries that had an auto rifle like galil and AK users would informally issue R4 50 rounders or RPK mags to be carried in the rifle for responding to ambushes, you can see this practice recurring in Ukraine with D60s and similar, so it obviously has merit to carry at least one larger mag; but the practice never took off in the west. Even when appropriate mags are available in inventory we don't seem to do it, like I remember the M27 was originally supposed to be issued with surefire casket mags, literally never seen them fielded once.
