Started in 2015, Keystone Munitions was formed with the intention of providing premium ammunition to the great state of Pennsylvania and surrounding areas. Family owned and operated, the goal was and will always be to provide premium ammunition while providing some of the best prices. One thing is for sure, we will never sacrifice quality over price, no matter the cost.

Our 9mm subsonic ammunition was designed to be quiet and extremely soft recoiling when fired through a suppressed firearm. A detailed load development process also ensured that this ammunition would run reliably in unsuppressed firearms as well. With or without your favorite suppressor, you’ll find this to be a great option for a smooth cycling, low recoil subsonic 9mm ammunition. Conveniently packed is 250 round bulk packs. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases. 1 bulk packed box of 250 rounds.
