It depends on whether you're using the term machine gun by the military definition, which normally implies a crew served or general purpose weapon, or just referring to a full auto weapon in general.
For the former, no.
For the latter, most hand held machine pistols were designed to be used with a buttstock, but were compact and/or balanced enough that their design could facilitate one handed firing out of necessity, if need be, with some examples including the Uzi, Mini Uzi, Micro Uzi, Ingram MAC-10 and MAC-11, Skorpion, Cz. 25, etc.
Additionally, there were full auto variations of some handguns, including the Beretta 951R (full auto variant of Beretta Model 51), Beretta 93R (full auto variant of Beretta 92), Glock 18 (full auto variant of Glock 17), and the Stetchkin (although it might be a bit bulky to be considered a practical "pistol").

None. The Cold War was a "war" of nerves, words and political maneuvering. There were no guns involved (that's what made it a "cold" war).
No. Machine guns will beat Gatling guns.
They didn't really have machine guns, per se. They had some rapid fire weapons which could be considered predecessors to machine guns, such as the Gatling Gun. The advantage it provided was much the same as what modern machine guns provide - a high casualty producing weapon with suppression capabilities.
Machine guns.
All sides involved did.
The Maxim, Vickers, Lewis, Springfield M1917, and Schwarzlose machine guns were all of comparable efficiency.
