This is a rant thread.

It bothers me to no end that triple stack magazines can not be made. If they were possilble, we could have 50+ round capacity 5.7 pistols and mag-in-grip PDWs. A machine pistol could fire continuously for longer than the current 1.5 seconds or so. They might actually become useful. We could triple stack large case head cartridges that preclude quad-stacking, like 308. Those could use 40+ round mags. It would be sick. But no, it’s just a property of the universe than magazines must stack in powers of two.
