When It comes down to it, a .22 round can definitely be lethal. It may sound weird, but I would totally trust my life with this thing (and my shooting skills of course).
And if you want to be extra sure, pop in some high velocity (1,600fps) rounds. These MP5 "clones" are absolutely awesome, and...
This gun never disappoints... rarely ever jams and is SUPER ACCURATE!!!
Its compact design and folding feature make it easy to stow and go.
The sub 2000 is extremely effective either bone stock or covered in accessories.
Watch as this weapon proves to be one of the finest defense weapons! ENJOY!
