The PPSh-41(Pistolet-Pulemyot Shpagina)nicknamed "Pah-Pah-sha, Shpagin and Burp Gun" submachine gun was one of the most mass produced weapons of its type of World War II. It was designed by Georgi Shpagin, as an inexpensive alternative to the PPD-40, which was expensive and time consuming to build. The PPSh had a simple blow-back action, a box or drum magazine, and used the 7.62x25mm pistol round. It was made with metal stampings to ease production, and its chrome-lined chamber and bore helped to make the gun very low-maintenance in combat settings.
The PPSh-41 (Pistolet-Pulemyot Shpagina) Shpagin Machine Pistol; nicknamed "Pah-Pah-sha, Shpagin and Burp Gun" submachine gun was one of the most mass produced weapons of its type of World War II. It was designed by Georgi Shpagin.
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 classic example of a design adapted for mass production
Retired from Soviet Army service soon after the WW2, the PPSH was widely exported to some pro-Soviet countries around the world, including Vietnam and many African countries.
The main advantage of the PPSch-41 was bigger effective range (when compared to both Allies and Axis submachine guns of that era). It also was accurate enough and reliable.
Some of the PPSh's drawbacks included the difficulty of reloading, the tendency of the drums to jam (solved by the box magazines) and the high risk of accidental discharge when dropped - the last being a fault common to all open bolt submachine gun designs.
Now if your looking to own one of these rare peices of Solviet history, good luck finding one to buy. whole weapons are hard to comeby. You would be better off find parts and making and putting it together yourself.
