Cant Shoot Or Unlimited Ammo

Is there a way to make it where they cant Fire the Weapon until the Match starts ( In Lobby with Weapon in Hand) or Unlimited Ammo on the Weapon but when match starts have a Set Amount. Ive tried a couple things like try to make the Weapon spawn in there hands when the game started from Level BP but it dont work due to how many Characters i have to select from, so only thing i can do is add the weapon to each Character separately (Base Character wont have any weapon)

Figured It Out, with ammo set up and Max ammo set up just make it where the HUD with the Magazine Amount and Max Ammo Amount would be shown when playing not show in lobby and you have infinity ammo then when your character loads in has a set amount
