Well it's pretty basic.

The regular Uzi has the longest receiver, and the heaviest bolt, the Micro Uzi has the shortest receiver, and the lightest bolt, to the point that the Micro Uzi has a tungsten weight added to the bolt to give it more mass, as it was even faster otherwise, being outright dangerous to handle
(and honestly, it arguably still is, it REALLY isn't a weapon someone can just pick up and use, you need a lot of practice and familiarity with it, the Mini Uzi is a safer and more practical bet 9 times out of 10).

More weight, and more room for the bolt to travel, means more time between shots.
I figure you might be able to make the Micro Uzi cycle even slower by putting a heavier weight on the bolt (though I don't know how this would affect felt recoil), and then redesign it to have a rate of fire limiter, like the old Czech Scorpion has.

You get the same thing with pistols, they inherently cycle fast, so if it can fire in full-auto, it will fire very, very fast, the Micro Uzi gets into this territory.
