As someone who has all 3... (Destiny)

Once I got it upgraded / got used to it, I was able to very quickly take out enemies at a little beyond Fellwinter range. That plus never worrying about ammo makes it worth it to me. Plus it's range advantages will become more apparent once Shotguns get the nerf they've needed for months. I use Dreg's Promise on my Juggernaut Shielded Titan and compliment it with a longer ranged primary like Three Little Words or my lucky Badger CCL. In this role a Sidearm excels and helps keep me safe from even things like Fellwinter's Lie type shotguns. It's certainly a choice with drawbacks, but I've actually replaced my Invective (which has always been my go to short range special) with Dreg's Promise in the Crucible and am very satisfied with the results.
