let security officers swap their guns at secvends

[KikiMofo]

to the contrary i feel like all it really takes for a person to be turned off from using a particular gun (much like a job which i've both seen and experienced) is a bad round and feeling like you never want to use or experiment with a particular gun again, something i feel outweighs the potential "reward"

True. Someone uses a gun one round and doesn't have fun with it so they never use it again.
I do like the idea for experimentation.
