The PPSh-41 (Pistolet-Pulemyot Shpagina; Russian: Пистолет-пулемёт Шпагина; "Shpagin machine pistol") is a Soviet submachine gun designed by Georgi Shpagin as an inexpensive, simplified alternative to the PPD-40. Intended for use by minimally-trained conscript soldiers, the PPSh was a magazine-fed selective-fire submachine gun using an open-bolt, blowback action. Made largely of stamped steel, it had either a box or drum magazine, and fired the 7.62x25mm pistol round. The PPSh saw extensive combat use during World War II and the Korean War. In the form of the Chinese Type 50 (a licensed copy), it was still in use in Vietnam with the Viet Cong as late as 1970. According to the 2002 edition of The Encyclopedia of Weapons of World War II the PPSh is still in use with irregular military forces.
World War IIEdit
The impetus for the development of the PPSh came partly from the Winter War against Finland, where it was found that submachine guns were a highly effective tool for close-quarter fighting in forests or built-up urban areas. The weapon was developed in mid-1941 and was produced in a network of factories in Moscow, with high-level local Party members made directly responsible for production targets being met.
A few hundred weapons were produced in November 1941 and another 155,000 were produced over the next five months. By spring 1942, the PPSh factories were producing roughly 3,000 units a day. The PPSh-41 was a classic example of a design adapted for mass production (other examples of such wartime design were the M3 submachine gun, MP40 and the Sten). Its parts (excluding the barrel) could be produced by a relatively unskilled workforce with simple equipment available in an auto repair garage or tin shop, freeing up more skilled workers for other tasks. The PPSh-41 used 87 components compared to 95 for the PPD-40 and the PPSh could be manufactured with 7.3 machining hours compared with 13.7 hours for the PPD. Barrel production was often simplified by using barrels produced for the 7.62mm M1891 Mosin–Nagant rifle: the rifle barrel was cut in half, and two PPSh barrels were made from it after machining the chamber for the 7.62mm Soviet submachine gun cartridge.
The PPSh was popular in the German armies as well, and captured examples were frequently returned to service against their former owners. Because of the very close dimensional similarities between the Soviet 7.62x25mm Tokarev and the German 7.63x25mm Mauser cartridge used in the Mauser C96 pistol, the PPSh could fire either cartridge, and was thus easily supplied with ammunition. In fact so many were captured that it became the second-most-common submachinegun used by German forces.
After the German Army captured large numbers of the PPSh-41 during World War II, a program was instituted to convert the weapon to the standard German submachine gun cartridge -9mm Parabellum. The Wehrmacht officially adopted these converted PPSh-41s as the MP41(r); unconverted PPSh-41s were designated MP717(r) and supplied with 7.63x25mm Mauser in place of the Soviet 7.62x25mm cartridge. German-language manuals for the use of captured PPShs were printed and distributed in the Wehrmacht.
The Soviet Union also experimented with the PPSh-41 in a close air support anti-personnel role, mounting dozens of the submachine guns in forward fuselage racks on the Tu-2sh variant of the Tupolev Tu-2 bomber.
Over 6 million PPSh submachine guns were produced by the end of the war. The Soviets would often equip whole regiments and even entire divisions with the weapon, giving them unmatched short-range firepower. Thousands more were dropped behind enemy lines to equip large partisan formations to disrupt German supply lines and communications.
After the war, the PPSh was supplied in large quantities to Soviet client states and communist guerilla forces. The North Korean People's Army (NKPA) and the Chinese People's Volunteer Army (PVA) fighting in Korea received massive numbers of the PPSh-41, in addition to the North Korean Type 49 and the Chinese Type 50, which were licensed copies of the PPSh-41 with small mechanical revisions. The weapon was widely used during the entirety of the Korean War. Though relatively inaccurate, with a high rate of fire, the PPSh-41 was well-suited to the close-range firefights that typically occurred in that conflict, especially at night. U.N. forces in defensive outposts or on patrol often had trouble returning a sufficient volume of fire when attacked by companies of communist infantry armed with the PPSh-41. Some U.S. infantry officers ranked the PPSh-41 the best combat weapon of the war; while lacking the accuracy of the U.S. M1 Garand or carbine, it provided more firepower at short distances. As one infantry captain stated: "on full automatic it sprayed a lot of bullets and most of the killing in Korea was done at very close ranges and it was done quickly - a matter of who responded faster. In situations like that it outclassed and outgunned what we had. A close-in patrol fight was over very quickly and usually we lost because of it."
 The PPSh-41 on display.The PPSh-41 fired the standard Soviet pistol and submachine gun cartridge, the 7.62x25mm (Tokarev). Weighing approximately 12 pounds (5.45 kg) with a loaded 71-round drum and 9.5 pounds (4.32 kg) with a loaded 35-round box magazine, the PPSh was capable of 900rpm, a very high rate of fire in comparison to most other military submachine guns of World War II. It was a durable, low-maintenance weapon made of low-cost, easily-obtained components, primarily stamped sheet metal and wood. The final production PPSh had top ejection and an 'L' type rear sight that could be adjusted for ranges of 100 and 200 meters. A crude compensator was built into the barrel jacket, intended to reduce muzzle climb during automatic fire. The compensator was moderately successful in this respect, but it greatly increased the muzzle flash and report of the weapon. The PPSh also had a hinged receiver to facilitate field-stripping and cleaning the weapon. A chrome-lined bore enabled the PPSh to withstand both corrosive ammunition and long intervals between cleaning. No forward grip or forearm was provided, and the operator generally had to grasp the weapon behind the drum magazine with the supporting hand, or else hold the lower edge of the drum magazine. Though 35-round curved box magazines were available from 1942, the average Soviet infantryman in World War II carried the PPSh with the original 71-round drum magazine.
A copy of the Finnish M31 Suomi magazine, the PPSh drum magazine held 71 rounds. In practice, misfeeding of the spring was likely to occur with more than 65 or so cartridges. In addition to feed issues, the drum magazine was slower and more complicated to load with ammunition than the later 35-round box magazine that increasingly supplemented the drum after 1942. While holding fewer cartridges, the box magazine did have the advantage of providing a superior handhold for the supporting hand. While the PPSh was equipped with a sliding bolt safety, the weapon's open-bolt design still presented a risk of accidental discharge if the gun was dropped on a hard surface.
After the German Army captured large numbers of the PPSh-41 during World War II, a program was instituted to convert the weapon to the standard German submachine gun cartridge -9mm Parabellum. The Wehrmacht officially adopted the converted PPSh-41 as the MP41(r); unconverted PPSh-41s were designated MP717(r) and supplied with 7.63x25mm Mauser ammunition (which is dimensionally identical to 7.62x25mm, but somewhat less powerful). German-language manuals for the use of captured PPShs were printed and distributed in the Wehrmacht.
During the war the PPS, an even simpler submachine gun, was introduced in Soviet service, although it did not replace the PPSh-41 during the war.

- Type 50: A Chinese-made version of the PPsh-41. Unlike its Soviet counterpart, it only accepts column-type box magazines.
- Type 49: A North Korean made version of the PPsh-41. This model only accepts drum-based magazines.
- K-50M: A Vietnamese-made submachine gun based on the Type 50s supplied by China during the Vietnam War. The chief difference was that the cooling sleeve of the K-50 was truncated to three inches (76 mm) and a foresight based on that of the French MAT-49 was attached to the front of the barrel. Modifications include the addition of a pistol grip, a steel wire-made stock and the shortened barrel. The changes made the K-50 much lighter by 500 g (1.1 lb) lighter than the PPSh41 at 3.4 kg (7.5 lb) as opposed to 3.9 kg (8.6 lb). The weapon uses a 35-round stick magazine, but the 71-round drum magazine can be used if the stock was fully retracted.
