Pindad PS-01
The Pindad PS-01 (Pistol Serbu, literally Assault Pistol) is a PDW-caliber pistol developed by Pindad. History
The PS-01 was developed by Colonel Rihahanto, who developed the pistol from August to September 2007. Working models were first shown at the 2008 Indo Defence Expo & Forum. After field tests were conducted, the Indonesian military dropped the PS-01 from consideration since it did not have full auto capabilities. Development
The PS-01 can be equipped with a silencer on the barrel with pistol-based tactical accessories attached underneath the barrel. References
