GP-31 Grenade Pistol

The GP-31 is a breach-loaded grenade launcher module, affixed to a compact stand-alone platform to turn it into a sidearm.

It fires one explosive impact grenade, comparable to that used by the GL-21 Grenade Launcher, and needs to be reloaded every shot. The weapon's ammunition is extremely limited, 1 in the tube + 8 spare grenades in total, requiring them to be used sparingly. Ammunition pickups will only replenish 1 grenade, while supply pickups restore 2.

In addition to the obvious destructive applications, the weapon can still also be used to seal bug holes and destroy automaton fabricators, as you could with the GL-21.

The weapon gives Helldivers an option to take a second type of grenade into battle, as normally they're compelled to bring explosive types to use against base structures and direct crowd control.

Bugs

 * When equipped with the Hellpod Space Optimization booster, it has an unintended effect of giving the GP-31 a "one in the chamber" load, resulting in an erroneous 2-shots in the tube when deployed, giving you a total of 10 shots before running empty. This however, only happens once every deployment and will not happen if the booster is not equipped by anyone.
