New .32 S&W is loaded to less than original pressure and power levels to be on the ultra-safe side. I have a bunch of 'em and have owned a bunch more. New ammo works just fine. I use Mag-Tech. If the gun is sound, it shouldn't be harmed by new .32 S&W ammo.
A Makarov? Simple, easy and works perfectly every time. ¡Vale!
