The Yugoslavian M49 (Model 1949) submachine gun at first glance appears to be a clone of Soviet PPSh-41 submachine gun. On close examination. however, there are more than a few differences between those two guns, with some features (most notably the bolt group and safety) being taken from Italian Beretta M38A submachine gun. It must be noted that M49 had apparently a relatively short service life, being replaced by the latter M56 submachine gun, which was more compact and of slightly more modern design The M59/57 designation refers to a later upgrade of the original 1949 weapon
