What about the Five SeveN? Would you call that innovative? I don't know if I would be interested in buying one based on the price for the gun and the proprietary ammo. But, I feel it is interesting and innovative.
I have really only handled/shot an FNP9 that my brother has. It seems pretty nice. Seems very well made and I really like the way it fits in my hand. Don't think I would it innovative though.
