Beretta M9 Commercial 9mm

This legendary semiauto handgun has not only won the historic contract with the US military in 1985 but has achieved a triumphant contract renewal after more than two decades of hard use in the world’s toughest and most extreme conditions, from the scorching deserts of Iraq to the frigid heights of the Afghan mountains. A contract renewal after this kind of use and abuse means a product that has kept its promises–and then some. Simply put, there is no pistol today that is as durable, reliable, dependable, easy to use, safe, and accurate as of the Beretta M9, the handgun that has rightfully earned the nickname of “World Defender.” Specs.
