StrangeRanger Posted March 17 Report Share Posted March 17 (edited) Got Uzi and I finally got the 9mm Para barrel for my Yugoslav M49/57 together. It simply refuses to run on US spec 9mm; it short strokes and drops the empties back in the ejection port. I know that Euro spec 9 is a bit hotter than ours but I also know that a lot of SMGs such as the Swedish K are designed to run on very hot ammo, far above the standard spec. I suspect that this is the case with the Yugo. Does anyone know for certain what ammo the 9mm version of the M49/57 was designed to use?
