Editor’s Note: The Beretta APX Centurion is a continuation of the APX pistol series from Beretta. It comes in two models -- a 9mm or .40 S&W -- both striker-fired. Overall length measures 6.97 inches with a 3.7-inch barrel. Though no longer in production, the Centurion can still be found in the used market. It's a decent CCW option for those that like a good mid-size gun.
