I have a couple of questions regarding weapons crates. 1. how many different guns can be stored in a weapons crate? In other words can I have an ak-47 and usas-12 in the same crate and exchange either one with a primary weapon that I am carrying? 2. related to the first, if I store my only primary weapon in an empty primary weapons crate then I no longer have a primary weapon because I have nothing to exchange it with, until I find or buy another one...which leaves me vulnerable. How do people deal with this situation?
