One of the more interesting, but generally unnoticed areas of developments is the PDW (Personal Defense Weapon, or pistol replacement). A recent design shows how compact and lightweight a powerful machine pistol can be. The Russian PP-2000 PDW uses 9x19mm round (the most widely used pistol round ever). The PP-2200 weighs 1.4 kg (3.1 pounds) has a 183mm (7.2 inch) long barrel and can use 20 or 40 round double stack (short) magazines. It has a folding stock so it can be used like a pistol or a submachinegun. You can attach a red dot sight and light (to the bottom). When folded up in “pistol” mode it will fit in a jacket. In the West there has also been a lot of PDW work. In 2010 for example the Rock River Arms PPS (Performance Piston System) Pistol appeared. This is a 5.56mm weapon that uses a new internal design. It has a short gas piston, with the recoil spring and guide rod over the 21cm (8 inch) barrel. The entire weapon (which does not have a stock) is 44.5cm (17.5 inches) long and weighs 2.2 kg (5 pounds). There are single shot and full automatic versions, each costing $1,335. There have been some notable European PDW designs from the major pistol manufacturers like H&K.
