Beretta's new Px4 Storm is built around a modular concept so that this single handgun can be adapted to different shooters. Configure the grip size, length of pull, magazine capacity and trigger mechanism; choose from four types of mechanisms, three of which are available only to law enforcement. Chambered in 9mm and .40 S&W, the Px4 comes with two magazines, three for law enforcement. Price: $630. Contact Beretta USA, Dept.
