So i was messing around in customs... and i decided to try to get the "magnum" to 3 shot kill like the halo 1 pistol. After changing a few things i got it to work!

I changed damage resistance to 90%, and weapon damage modifier to 150%. Since i did that, i turned grenades off, and made weapons on map AR. (Since AR is secondary and you cant put magnums on map)

I forgot to set the "leader traits" to start with pistol, so you'll see me not have it a few times, if your wondering why i dont.
