Kept seeing people call this weapon bad, but I've been having a blast and lots of success with it. Figured I would post my build, since it seems to work so far. This is the build I was using before I got a riven, I dropped [Heated Charge] for my riven (my riven adds heat and damage at the cost of crit damage).
I've been running steel path with this build for the majority of the day and having great success with it against grineer and infested. I have yet to test against corpus, but I suspect as long as I break the shields with a gun I'm sure it will [Shred] the health with ease.
