They are the perfect guns for personal and home protection. That is, the FiveSeven and the PS90.
The good:
Light, carry an enormous number of rounds, extremely dependable, very lightweight for the firepower contained, 30 rounds in a handgun and 50 rounds in a lightweight bull pup is sheer genious; backed by a technologically advanced firearms megagiant who will provide excellent support at all times;
The bad:
Arms are costly and ammo is costly
No real proof of someone reloading the ammo themselves
The master of arms of the PS90 is unusual enough that a bit of training is required before just handing someone the gun; the FiveSeven is ready to use in 5 minutes.
So, the net net is:
If you have the money and an hour of your time to forget what you know and realize that you are learning something all new, that it's not a joke and isn't time for fun, then it can be a huge success
You also have to be sure that you can buy and store a great deal of ammo (ten thousand rounds for two people with the guns as a starter) and multiples of that for others.
But that's it really. Just get the guns, secure the rounds with cash, train an experienced shooting team for an hour and you're good to go.
