The Singaporean concern of ST Kinetics (Singapore Technologies Kinetics Ltd) is no stranger to the defense market, having been founded as far back as 1967 and employing over 7,000 persons worldwide. The company has designed, developed, and headed production on a variety of systems for the Singapore military as well as foreign customers that include Heavy Machine Guns (HMGs), tracked Self-Propelled Artillery (SPA) vehicles, field mortar weapons, Armored Fighting Vehicles (AFVs), and personal small arms. In 2008, it debuted a new machine pistol/submachine gun product of modular design and supporting the ubiquitous 9x19mm Parabellum cartridge - the CPW ("Compact Personal Weapon").

As its designation suggests, the CPW was developed with compactness and lightweight functionality in mind - serving well for police, security units, and even special forces operatives in need of a small effective weapon. It fires from a low-recoil, lever-delayed blowback action at a rate up to 1,000 rounds per minute from a 30-round detachable box magazine. While no iron sights are fitted (they remain an optional accessory), the CPW is an all-modern offering by way of its support for accessories through an MIL-STD-1913 rail over the receiver and another section under the fore-end. Optics and aimers can therefore be sat over the receiver and a vertical fore-grip or tactical flashlight can be installed under the muzzle. Overall weight of the gun is 3.3 lbs with an overall length of 19.7 inches. The shoulder stock can be collapsed to promote a more compact profile nearing 13.8 inches in length. The barrel measures just over 7 inches long.©MilitaryFactory.com
The standard chambering is the 9mm German pistol cartridge which has seen widespread use around the globe for over 100 years. Other forms seen have chambered the Belgian 5.7x28mm (of the FN P90 series SMG) and German 4.6x30mm (of the HK MP7 PDW) cartridges - no doubt to challenge those guns' existing place in the military and civilian markets. A level control along the side of the receiver allows for semi-automatic fire or full-automatic fire.

Its general design approach mimics that of the famous Israeli UZI submachine gun in that the CPW has a hollowed pistol grip near the center mass of the weapon where the magazine is inserted. This provides good balance for the shooter and allows for a longer barrel to be seated within the protected length of the receiver. The grip handle is made translucent as a "quick-check" feature of the current ammunition count in the magazine. The shoulder stock is fully collapsible into the design of the CPW and, at the business end of the weapon, the barrel protrudes just a short distance ahead of the gun body with a slotted flash suppressor.©MilitaryFactory.com
