9mm Subsonic Practice ammunition typically uses heavier bullets, most commonly 147 grains, loaded to velocities below the speed of sound to eliminate the supersonic crack. These range ammo loads are widely used with suppressors and for quiet range training while maintaining reliable cycling in most semi-automatic pistols and carbines. Pricing generally runs slightly higher than standard 115–124 grain practice ammo due to heavier bullets and lower production volume. The products listed above span multiple manufacturers offering subsonic training loads, so daily price movement reflects the full retail mix.
