Used in Czech CZ-52 and Yugo M-59(?) Tokarev pistols. Also used in sub-guns in the same countries. Nominally an 86gr FMJ bullet at ~1500fps out of a pistol. Unreliable reports state that the sub-gun ammo was hotter but there is general disagreement that ammo was segregated between pistols and sub's. Same case head as the 9x19 so think of it as a 9x25 necked down to 7.62.
