Russian Subs - Small Arms

[Nefarious]

Question for the Sub Gurus, What kind of Small arms did Soviet Submarine crews carry in the 1950s?

I collect Communist Surplus Firearms and got into a discussion on another forum about the matter.

I would assume they would have Soviet Pistols like the Tokarev and possibly PPSH Sub machine guns, but I am not quite sure.

Any help would be appreciated, Pics of Soviet Submariners with small arms would be awesome!
