If two people were to use the exact same weapon, with the exact same nexus, and neither of them preferred that nexus, they'd be able to channel the same types of magic.
By putting nexii into different objects, it changes how the nexus channels magic through the object. Think of it as pipes: If you put an s bend where there was a straight pipe, there's probably different flow rates, travel time, pressure, etc. (Clarification: I am not a plumber)
The Nexus guns the goons have are just basic guns; they bestow a small amount of elemental power into a bullet*
**;DR - Nexus power is affected by preferred nexii, and object it is used in.
