A pistol version of the GP-12 Phased Pulse Rifle, this was formerly the issued sidearm for soldiers in the Star Army of Yamatai. It was partially replaced in YE 27 by the Nekovalkyrja Service Pistol, Type 27 and then phased out once the Nekovalkyrja Service Pistol, Type 28 was made standard in YE 28. Made by WickedArms Industries.

Price: Available for 299.99 KS at a Star Army Surplus Store, if you're a Star Army veteran. Civilian versions are sold elsewhere for 150 KS.

The GP-13 is a smaller weapon system based on the GP-12. Small, ultra-light, and possessing a respectable damage output, the weapon finds a home in many sidearm holsters of Star Army officers and crewmen, since it was once the standard sidearm (to be partially replaced by the Type 27 NSP and later completely replaced by the Type 28 NSP). It has all the features that made the GP-12 a success: EMP shielding, combination laser/light system, and even a small rail mount system. The GP-13, however, is built of aluminum carbide.

• Ammunition Type: 0.67mm/0.1 sec 120 MJ pulses from BU-P30 or BU-P30R battery magazine
• Weight: 0.5 lb.
• Length: 5“

As a pistol, the 13 is insanely light and with incredible range – it's essentially the core element of a GP-12B with a smaller battery. It's made of aluminum carbide, so the pistol lacks the outright ruggedness of the Nekovalkyrja Service Pistol, Type 28 and other NSPs. Their tendency for overkill is renowned. They're still seen in the Star Army, but not often, as chargers are rare for the batteries. They're all over the civilian market however, almost always with the military-grade ranges and destructive power removed by Yamatai armories before being released. These are nicknamed “GP-13Cs.” Cheap as hell.
