The PPP-79 (Plasma Pulse Pistol 2179) is the standard issued sidearm of the Yumtja military. It is in fact one of the best weapons that the Yumtja have to offer.
When the Yumtja rebellion needed a weapon; Don Rogers assisted in creating a new sidearm that would help better the defense of their people. He developed a pistol that was powerful enought to actually take down Colonial Marines within seconds; in other words the PPP-79.
The pistol remains the best sidearm that the Yumtja possesses and is known to be an extremely advanced piece of technology that they possess under the category of defense.
