7.62mm Submachine Gun Model 43/52 (7,62mm pistolet maszynowy wz. 43/52) is a Polish version of Soviet PPS-43 submaschine gun. (Also known in Poland as 7,62mm pistolet maszynowy wz. 43). Submaschine Gun Model 43/52 is a simple blowback operated weapon which fires from open bolt. Gun has receiver and barrel shroud manufactured from steel stampings. The cocking handle is located on the right side of receiver. Safety which locks trigger seat and bolt is located under the receiver in front of trigger guard. The weapon could be put on safety either with bolt in its front or rear position. The trigger mechanism without fire selector is for automatic fire only. The gun is chambered for 7.62x25mm cartridge and is fed from double column, double feed 35-round curved magazine from PPS-42 or PPS-43. Magazine well is located under receiver in front of steel pistol grip clad with wooden or plastic panels. Magazine latch is located between trigger guard and magazine well. PPS-43 was equipped with steel folding stock, but Submaschine Gun Model 43/52 was built with short fixed wooden stock only containing compartment for the cleaning kit. Mounting of the stock was achieved by means of two steel inserts with holes for the screws which eliminated the need for rear wall of the receiver and the folding stock hinge. SMG Model 43/52 is heavier than PPS-43. The chrome plated barrel has 4 grooves with right hand twist. Muzzle is terminated with a recoil compensator. The gun is equipped with open front sight and flip type L-shaped rear sight set either for 100 or 200 meters. Production of PPS-43 started on a small scale in "H. Cegielski" metalworks in 1946, but in late 1951 a mass production of PPS-43 had begun in "H. Cegielski" metalworks, Radom State Arsenal, "Baildon" ironworks, and "Wifama" textile machine factory. SMG Model 43/52 had been manufactured in "H. Cegielski" metalworks, and Radom State Arsenal since late 1952. PPS-43 and SMG Mod. 43/52 were used in Polish Armed Forces until 80-ties, but some paramilitary government organizations such us Industrial Security (Straż Przemyslowa) and Railway Defence Formation (Slużba Ochrony Kolei) used them until 90-ties.
.6mm Submachine Gun Model 43 (5,6mm pistolet maszynowy wz. 43) is a Polish training version of PPS-43 utilizing .22 Long Rifle rimfire cartridge. The weapon was designed in 1955 and it was produced in short series by "Wifama" textile machine factory. 5.6mm SMG Model 43 is a simple blowback operated weapon firing from an open bolt. The trigger mechanism is for automatic fire only. Weapon is equipped with a steel stock folding on top of the receiver. The gun has redesigned aluminium bolt and recoil spring. The concept of the SMG Mod. 43 "trainer" was based on the use of 7.62x25mm cartridge look-alike aluminium inserts. Each of such inserts had to be loaded with .22LR cartridge. The inserts were resuable, therefore there was a need for a shooter to collect ejected "shells" for repeated use. The gun was fed from standard double column, double feed 35-round curved magazine from PPS-42, PPS-43, and SMG Mod. 43/52 submaschine guns. Interesting is a fact, that concept of the "trainer" was also utilized in Polish 5.6mm Pistol Model 33 Sport (5,6mm pistolet wz. 33 "Sportowy"), which was based on Soviet TT-33 pistol.
