I rencently seen the 1 slot weapon thing

I would like to start getting the Golden Eggs + with the one slot weapon.

If I want to survive +30mins, whats the best weapon I can pick as 1st?

Also, when u select only 1 weapon slot, if the map has no weapon items, there's no way of getting any other right?

(choosen Trouser as the Golden Egg guy as everyone says is good :P, any recomendation?)
