Depends on the version. FG42 Ausf. E had about 900 rounds, while the Ausf. G had 750 rounds. UZI is iirc about 600 to 650 rounds (only had this in Bundeswehr time as MP2). Also there were even more Ausf. from the FG42
Still the 8mm Mauser packed a punch like a donkey. Even more than current nato 7,62 rounds. So "rarely" is kinda underrated
And than this SMG behaviour is kinda bullshit. It should be semi automatic or "slow" automatic fire like in CoH1 with a good punch and not this pee shooter SMG style.
Dunno which model is used in Coh2, but I haven't found any sources saying that the RoF dropped to <600rpm with the later models (model II, which is what ausf G was called I believe, = 600-750rpm). Then there's other type of "uzi" nowadays with way higher RoF of course.
Yeah, "rarely" is probably an understatement, as wouren elaborates as well
. Probably only used with a bipod lmg style, or in close combat, and maybe sometimes just for shits and giggles..
To not deviate too much from topic, I do think I know what you mean now with "slow" automatic fire, not to slow down the actual rate of fire when the trigger is pressed but to make burst shorter with higher damage? I don't know how it was in coh 1.
