A hand gun ( pistol ) round on average hits the ground at around 400 meters. I'd think that at around 50 meters it would still have a fair amount of velocity. The average map size in destiny wouldn't be more then around 100 meters in length, with the 2.0 patch the hand cannon ( if you want to compare it to a hand gun) won't get you a kill in three head shots outside 30 meters, not to mention the stability at that range.
