That sounds like the Drakon again. The burst sniper isn't exactly what I'd call rapid. It shoots a 3-shot burst, yeah, but it has to charge up each time you press the fire button. Makes it at least as slow as the Locust, if not moreso, without the benefit instantaneous fire. The actual burst is so quick that you can't really utilize it that well to correct your shot in mid-burst (at least, not on console), and hitting players with more than one shot tends to be overkill in most situations.
Make a paintjob of the pistol or whatever with different words on either side. Then make a variant of that pistol with dual wield and the paingjob equipped. Then give that variant to your specialist as their showcase weapon. You might have to have dual wield unlocked to be able to equip the variant. I'm not sure.
