Custom games question - no ammo

Hello,
I have a burning question, regarding how to lower player ammo counts at the beginning of the game. I’m struggling to get the ammo at the start of a match zero or less than a mag. I have been in some games where the you start with a pistol with less than one mag.

Anyone know now how to do this? I need it for player starting weapons as they immediately have to pick up a weapon, so I don’t want them killing each other off spawn.

Thanks in in advance if you can answer my predicament!

Update

How did you get this to work?
