Not sure if anyone cares but it has the choice to use either extended mag or armor piercing rounds. It's possible to get faction rally gear early from opening the chests marked by treasure maps that you can buy from Cayde.

You can also get the FWC auto, and the Dead Orbit hand cannon and pulse rifle. Those are the only ones I've seen people get. I have the DO hand cannon and it's badass.
