There's a, uh, 15 day wait on the handguns but the rifles you can take right now,- you can't do that.
The Five-seveN has been loved and hated in the years since its introduction. It is one of the most controversial handguns of our time, and was so even before the Fort Hood atrocity.
It has been acquired by myriad special police groups, but in the military it is used by Belgian pilots, Cyprus special forces, Mexico, Nepal and Spain. This is quite a feat as it has always been a difficult task to launch a new calibre on the military market, especially for handguns.
