Been looking at picking up one of the Serbian M70AA versions of this pistol as a curiosity. By today's standards the TT-33 family is heavy and ungainly, and REALLY old-fashioned looking, but in military service over the decades it was apparently solid and reliable.

For anyone with experience, is the 9mm version worth picking up over the 7.62x25mm gun? Seems that 9mm ammo would be easier and cheaper to come by.
