Earlier this year at the Singapore Airshow, Singapore Technologies Kinetics, otherwise known as ST Kinetics or STK, the Singaporean firm who make the Ultimax 100 machine gun, announced their a new PDW (Personal Defense Weapon) type sub machine gun called the CPW (Compact Personal Weapon).

According to the STK brochure and the pieces of info I picked up on the internet:

  • Can be holstered
  • Lighweight
  • 7″ Barrel
  • Multi-caliber. Currently available in 9mm (30 round magazines)
  • Translucent pistol grip to check rounds in the magazine
  • Comes standard with reflex sight. Iron sights are an optional extra.
  • Retractable stock
  • Low recoil
  • Low cost


Length: 350mm
Barrel Length: 180mm (7″)
Mounting system: 2 sets of picatinny rails
Weight without accessories: 1.5kg (3.3 lbs).
Firing modes: semi and auto (selector can be seen on above photo)
Method of operation: delayed blow back
Rate of fire: 900 to 1100 rpm.

I would assume they will also offer a typical PDW round such as the MP7’s 4.6x30mm or the P90’s 5.7x28mm.

The gun looks very similar to the MP7 and I think would be in direct competition with it. It weights less (MP7 weights 4.19 lbs/1.9kg), is slightly shorter in length and has a similar rate of fire. I think the CPW’s main selling point is cost.

A couple more photos:

This looks like a prototype. It has a slightly
different trigger to the one above.
