The PPSh-2 is a prototype Soviet submachine gun.
The PPSh-2 was designed by Georgy Shpagin to fulfill certain requirements, and it was trialed in 1942 by NIPSIVO, the Red Army Scientific and Research Proving Ground for Small arms. It was liked by the testers, so a small batch of around 200 to 250 weapons were produced. However, the PPS submachine gun was preferred over the PPSh-2, and as such the PPSh-2 faded into obscurity.
The PPSh-2 is a weapon that uses blowback and fires in fully automatic only. The charging handle is located on the right side of the weapon and is protected by a dust cover.
