Alright condescending @Rob, calm down. The correct and polite response would be: Unfortunately, your question isn't so easy to answer. There are many types of 9mm rounds to choose from. Your best bet would be to either call them on the phone or drop by in person. The staff would be glad to help you I am sure. Good luck and happy shooting!
Tbhh im very new at this my instructor just said 400 rounds of 9mm factory ball ammo brass casing.
