Imagine being attacked with lethal force.
For 5-10 seconds - count ‘ em! - while fiddling with something mechanical.
Then do it again a few seconds later.
Think you might end up dead during that 10-20 second useless period?
I’ll stick to 30 round mags.
I’ll get some 100 rounders while I can.
And I’ll consider an enemy anyone who would ruin my life for owning them.
I guess we’ll have to go back to belt fed weapons.
