In this regard, in 1940, a competition was announced for the creation of new models of the German anti-tank guns, which were intended to replace singly PzB PzB 38 and 39. German designers have offered a number of experienced self-loading rifles with elevated anti-martial and performance, designed for use cartridge «Patrone 318." Tactical and technical characteristics of the presented prototypes PTR despite a strong variation in the designs were very similar, which was due to very strict conditions for the job. For tests were presented antitank rifles models 40, 41, 42, 43 and 44 of different manufacturers.
Concern «Gustloff-Werke» presented two self-loading sample anti-tank rifles - Model 42, to get the index «PzB 40 G» and Model 44.
