Descriptions:
The ADPI P21 UMC series is the improved version of ADPI UMC series, the P21 UMCs are called differently as their ammo cartridge differs, but all of them are considered single firearm.
As the original UMC didn't make its concept: "Allow all types of magazines" to the point, the designers and engineers came up with the improved concept: "Make the internal parts to be interchangeable to allow all types of magazines and cartridges to be used by this firearm". With few tools, this bullpup sub-machine gun can easily change its ammo cartridge at no time(That`s why the ejection port is much wider than the .45ACP magazine's width), which complements and improves the original concepts: "Universal" and "Compatible".
A P21 UMC has a short upper picatinny rail, an underbarrel laser sight/flashlight/lightsaber(which is also interchangeable), and a detachable foregrip as default, all of them are improved from UMC's concepts.

How to Lock n' Load:
As soon as the mag is empty, the slide automatically pops up(after being blown back with recoil) and locks the ejection port open simultaneously. Then the user re-loads the magazine and tap the slide downwards to unlock and load the fresh round into the chamber.
