Issue with "PDW" as a weapon category

[Evil Tim]

I don't so much mind having a cat for multiple barrel firearms of a certain type (rotary guns) since it makes it quicker to check through them all and it's a logical group, but I'd agree that the previous name was too broad; nobody really needs to look at all types of multi-barrel weapon to see if this minigun-looking thing they saw might actually be a double-barrel shotgun.
