If you can get your hands on the right Hand Cannon, you can absolutely shred your foes. I'd say The Last Word or Fatebringer can convert just about anyone to a Hand Cannon enthusiast. I always liked HC but I didn't use TLW as much simply because I lost a exotic slot on my primary when I had the likes of Icebreaker, Gjallahorn, Pocket Infinity and Thunderlord ready to rock and roll. Once I got the Fatebringer though, I was all in! Hand Cannon power with perks that explode enemies with precision kills and AoE damage for each round fired. The combination of these two perks makes groups of enemies a synch and drops larger enemies in a hurry. Also, there is a perk which increases reload speed with precision kills which makes the typically slow reloading of HC a non-factor. I've seen the Fatebringer convert avid AR/SR/PR users almost immediately. Did I mention that FB also does Arc damage?! Check Please!
