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. It is heavily recommended to deploy with the Hellpod Space Optimization booster as the player only deploys with 4 extra grenades for the launcher, which is hard to top-up completely due to the low replenish rate.

Role
In addition to the obvious destructive applications, the weapon can still be used to seal bug holes and destroy automaton fabricators, as you could with the GL-21. As a pistol, it is a one-handed weapon and can be fired on the move, or while holding an object.

Since it counts as an impromptu impact grenade, using the GP-31 gives Helldivers an option to take another type of grenade into battle as this already covers their explosive needs, expanding one's tactical flexibility, at the cost of reliable close-range defense.

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 hellpod deployment and will not happen if the booster is not equipped by anyone.
