I run into plenty of PPS users while playing as Low BR Germany but I rarely ever really pay enough attention to see which one they are specifically using.
(All I know is if I run into someone running an assault squad with full body armor in low BR they will certainly have a PPS in their hands instead of PPD-34)
maybe they are planning to move PPS to BR III with this new SMG and Reising Model 50 with 30 rounds that soviets got form LL maybe we can finally move PPS to BR III.
Not gonna lie, Pps42 and 43 would easily fit BR3 as they are.
Though Pps43 could get a recoil buff.
Yes and Uragan and Reising with 30 rounds at BR II will be good BR II more balanced options for USSR.
I used to use all PPS43’s. but prefer the PPS42 and use it with all my BR2 squads. I still arm my pilots with the PPS43, but only so I can still field them. 
Well, remember that these models are “temporary” and we would eventually get domestic models… probably after the bayonet for the FG42 and nationalities for soldiers.
so it will only stay this way for 4 year?
No they didnt. Its a different rifle just of Fedorov gun family.
As for who asked, there were people posting plenty of posts about it. For the rest I can agree
I would say at least two.
