MG-42's accurate enough, overheating is a problem with the volume of fire but changing barrels is super easy. Easier than changing barrels for the 34. The volume of fire is fantastic, and I'd prefer it over something slower like a Maxim or a Browning.
In German WWII reenacting there's a huge amount of K98ks followed by very few G43s and MP40s. Following them are STG44s and finally MGs.
In Soviet reenacting there's a bunch of Mosins, but the PPS-43 is plentiful for some reason. There's more of them then there are German automatics, haha.
Having a PPSh-41 with a round drum would be great. 72 rounds of face to face kill. But that's damn expensive. Also finding a good round drum that still works like a charm is a toughie. Most are so old now they jam more than they did back then. You'll usually see stick magazines.
