We actually have Will Ruger to thank
for that... it was postulated by him that as a compromise to firearm bans or confiscation, that a limit on magazine capacity would suffice to reduce the overall damage caused.
Ruger was a major FUDD despite founding Sturm Ruger Co. and said that "no honest man needs more than 10 rounds".
And of course, Ruger to this day is notorious for their firearms taking proprietary magazines, because that's how they make most of their money, not off gun sales, but the magazines and accessories that go with them.
In fact, it's actually how most firearms manufacturers make money, not through firearms alone.
