Removing ammo from a player on respawn?

I'm experimenting with a 1v1 map and I was wondering if there was a way to remove all of a player's ammo on respawn, leaving them with just melee until they respawn. If anyone could answer that would be greatly appreciated. Thank you!

 

I know it’s possible because jailbreak does it

 

that is done via sourcemod

 

the forced medieval mode prefab has a mechanic that causes a player to switch to melee on respawn. that may help unless i'm misreading what your concept is.
