Subsonic 9mm 

Subsonic 9mm is subsonic ammo that is made so the round doesn't break the sound barrier. It's travels at speeds below thr speed of sound, hence "SUB SONIC". The most common subsonic 9mm is typcially a 115 gn round and 1250 FPS. Below is our selection of subsonic 9mm freedom seeds from 4140 Armory.
