Weapon respawn on local Slayer?

Hey guys,

I am playing Halo 4 locally with 4 friends, and am having trouble with some settings.

Basically, I am playing Slayer, first to 10 kills. It seems like the weapons in the maps do not respawn, or take an incredibly long time to. So after the first few kills each, there’s nothing to pickup.

I looked through all the settings and couldn’t see one for this. Although there were a few settings that I wasn’t sure what was meant. Any help on this? Is it a simple setting I’m missing? Or I am in the dark completely, and am missing a key concept on how the weapons work?
