First choice in personal protection:
MP9 / TP9
The MP9-N is a 9x19mm caliber submachine gun/ Personal Defense Weapon (PDW); while the TP9 is the semi-automatic version. Both products because of the size cover a wide range of tactical applications. The compact size and superb ergonomics makes it ideal for bodyguards, covert surveillance, armed vehicle operations, and other specialty jobs where size and weight are an issue. Several NATO Air Forces use it as a bailout gun for downed pilots. It is the lightest and most compact 9 mm SMG/PDW on the market today. This MP9 was adopted by the Swiss Army under the designation MP14 as PDW.
