Re: new pistol?
It's a good pentrating round and it's not cheap for plinking; expect to pay around .40-.45 per round. It is a good handling gun and very fun to shoot. The P90 bullpup also shoots the 5.7 and it's one of my all time favorites to shoot. A friend has one and putting a few hundred rounds through it is an absolute thrill.
The 5.7 is a great shooting gun but I would recommend that you test fire one if at all possible and also do your homework on ammo. It's not much more than a .45acp to shoot and it is reloadable.
