The PM-38 was a Soviet 50 mm light infantry mortar, developed as a variant of the M-38 120 mm mortar. The barrel was clamped at two elevation angles only - 45 and 75 degrees. Range variations were made by altering a sleeve round the base of the barrel. This sleeve opened a series of gas ports which bled off exhaust gases and so determined the range.

The project was deemed overly complex and expensive, and was only produced for a short time, before being replaced by the Model 1939. Despite the small number produced, some fell into German hands in 1941, who introduced them as the 5 cm Granatwerfer 205/1(r).
