1vs1 fights Kiraly 39M no doubt.
It's an Hungarian gun with the 9mm Mauser export round.
It isn't the best looking gun but it sure is powerfull with an effective range of 300-400meters!It had a better effective range as the ppsh and the ammunition had a similar effectiveness (muzzle velocity 450m/s, bullet weight 8.3 gram, muzzle energy 840 Joules vs 525/s,5.5 gram,760joules.)
Had made a mistake sorry but i edited it.

And btw for the ppsh loveruring 1941-42 the Hungarian Army captured a number of PPSh-41 machine guns on the Eastern Front. These guns were re-issued to Hungarian troops. The troops did not like them, compared to the Hungarian Danuvia 39.M machine guns. The ammunition had a similar effectiveness, but the workmanship and reliability of the PPSh-41 was nowhere when compared to the 39.M. The biggest difference was in accuracy, as PPSh-41's barrel length was only about half of the M.39's. The 71-round drum magazine had a tendency of jamming if it was loaded with 65-68 rounds or more. However, the PPSh-41's shorter length gave it the advantage during house-to-house combat situations.
Only better in house to house so Russia PPSH wasn't the best for people who say it was.;P
