That's why.

In reality, this thing was the brainchild of Kalashnikov's son and the whole reason it was funded and received (limited) adoption was to give him a win for reasons of national pride. It was conceived to be a compact-sized LMG replacement for counter-terror purposes which would pair with steel-core ammo to defeat light cover/armor. In practice, the helical mags are unreliable and just plain awkward to carry. You have to use the same rig to carry RPK mags to carry PP-19 mags, and can only carry one 64rnd PP-19 mag in the same pouch that can carry x2 45rnd RPK mags. So the same loadout carries (less) of a (less) powerful ammunition, even if the gun itself gets more maneuverable.
