Performance
9×18mm Makarov is ballistically inferior to the 9×19mm Parabellum cartridge. While there are no official SAAMI pressure specs for the 9×18mm Makarov cartridge, tests indicate that surplus ammunition develop pressures in the mid 20,000 psi, significantly less than the 35,000 psi or more generated by 9mm Parabellum loads. As such it is designed to be used in low powered blowback semiautomatics, much like the .380 ACP cartridge, rather than locked breech designs encountered, but not always required, for higher pressure cartridges like the 9 mm Parabellum.
The 9×18mm Makarov cartridge is not interchangeable with the more powerful 9 mm Parabellum or 9 mm Largo, and its ballistic performance is much closer to the .380 ACP.

From their own music when they stray.”
