They were already using lighter weight Makarov pistols before the TP-82, and switched to the combo gun after some cosmonauts spent the night in the Siberian wilderness and thought a small semi-auto pistol wasn't enough. But, yeah, running out of qualified ammo likely just supplied the impetus to re-evaluate the necessity of the TP-82. More interesting is the laser pistol the USSR attempted to design for cosmonauts to carry. https://en.wikipedia.org/wiki/Soviet_laser_pistol https://en.wikipedia.org/wiki/Soviet_laser_pistol
