I'm not a big fan of +P ammo but in standard ammo, my PM9 has digested everything I've fed it including:
Remington Golden Saber 124 gr.To this point, absolutely no failures. However, I make no guarantees as every firearm, even same make and model, can perform differently.
Magtech FMJ, both 115 gr. & 124 gr.
Winchester White Box 124 gr. FMJ
Winchester Ranger 115 gr. JHP
Federal Tactical HST 124 gr. (current carry ammo)
CCI Blazer FMJ, both 115 gr. & 124 gr.
CCI Blazer Brass FMJ, both 115 gr. & 124 gr.
Federal American Eagle FMJ 115 gr.
