Yeah. It's a great weapon!
You just have to be cognizant of the Accuracy penalty and plan accordingly. (Perception + Accuracy boosting items, food, etc).
They fire multiple projectiles, and the attack is rolled for each projectile. This means you can get a critical hit on each projectile.
Furthermore, the modal (Powderburns) allows you to deal significant AOE damage at the expense of being Distracted. (-5 Perception, Flanked).
As a Streetfighter Rogue always using Powderburns, you always have -50% Recovery Time, and +50% Damage against flanked or afflicted targets. If you take Persistent Distraction, that's +50% damage all the time, AND -10 deflection on enemies, which essentially mitigates the -5 Perception if you use weapon attack abilities.
