More for contractors riding around in unarmored SUVs would be my assumed application, especially if there's no RPK with a drum around. Or tape two together for contact breaker applications, especially at night, when a little upright running to cover might reasonably be expected. I've always liked having one crap magazine for leftover rounds from 20-round boxes, pulling a couple of rounds from a mag to put counter tracers [You're almost out! You're REALLY almost out!] in. But 40 seems a bit much.
