Keep in mind the two that are for sale here are only semi automatic and have the 16+in barrel. The way I see it... it only takes one anyways.
Lol I like how the guy spins the gun to face him without even checking to see if its cleared. Scary that someone like that can own a fully automatic weapon.
As for the PS-90, it's a great gun especially for close quarters due to being compact and using smaller rounds. I like how the mag doesn't extend downwards like most rifles and also that the cartridges eject downwards as well.
