These cost-saving measures reduced the amount of machined components to a bare minimum, cutting down machining time by more than half (2.7 hours of machining required to complete a PPS as opposed to 7.3 hours for the PPSh-41). Savings of over 50% were also noted in terms of raw steel usage (6.2 kg instead of 13.9 kg) and the number of workers required to fabricate the individual components and conduct final assembly of the weapon.

Prototypes were evaluated successfully during the spring of 1942, after which the firearm was accepted into service later that year as the PPS-42 (Russian

Open bolt
A semi or full automatic firearm is said to fire from an open bolt if, when ready to fire, the bolt and working parts are held to the rear. When the trigger is pulled the bolt goes forward, feeding a round from the magazine into the chamber and firing it...

. The bolt was cylindrical in shape and contained a spring-loaded claw extractor, which pulled the empty case out of the chamber and passed it to the fixed ejector housed in the lower receiver. The charging handle was integral to the bolt and was located on the right side; it reciprocated during firing. The PPS originally had a fixed but replaceable firing pin, held in place by the extractor spring. Pulling the trigger released the bolt, which moved forward, stripping a round from the magazine, chambering it and striking the primer in one motion.

Features

The PPS had a trigger mechanism that allowed only fully automatic fire and a manual safety that secured them against accidental discharges. When in the "safe" position (engaged by sliding a metal bar forward of the trigger guard), both the bolt and trigger were disabled.

The weapon was fed from curved 35-round box magazines that were not interchangeable with magazines used in the PPSh-41; nor could the gun use drum magazine

, consisting of a strip of steel bent into a U-shape that deflected exiting muzzle gases to the sides and backwards, thus compensating for recoil.

A folding stock was attached to the receiver with a spring-loaded catch button on the left side. The stock folded up and over the receiver top cover and the weapon could be fired in this arrangement. The submachine gun also had a pistol grip

 but was not provided with a forward grip as the magazine well was intended to fulfill this role. The PPS was usually supplied with two magazine pouches, an oil bottle, bore brush and sling.

Sights

The PPS was fitted with a set of open-type iron sight

s consisting of a fixed front post protected from impact by two sheet metal plates and a flip rear sight with two pivoting notches, for firing at 100 and 200 m.

Variants

Towards the middle of 1943 the modernized PPS-43 entered production; efforts were made to improve manufacturing and safety. The ventilated heat shield was integrated with the upper receiver cover, both the barrel and shoulder stock were shortened, the stock's locking mechanism was simplified, the casing ejector was moved to the rear of the recoil spring guide rod, the magazine well angle was increased in the receiver in order to enhance feeding reliability and the safety was improved to block the trigger and lock the bolt in either the open or closed positions.

In the early 1950s Poland developed a modified version of the PPS-43, known as the PPS wz. 1943/1952 that replaced the folding metal stock with a fixed wooden buttstock. This was mounted to the receiver end plate using two inserts and the receiver take-down hook was bent downwards to accommodate the change. The buttstock has a compartment carved inside of it that contains a standard cleaning kit; the side of the butt has a sling loop. This modification was meant to increase the accuracy of the PPS submachine gun, but minimal gains in accuracy were offset by the increase in weight and size of the PPS wz. 43/52 in comparison to the original PPS-43.
