With crit factored in, Sandgun puts out 117.0 DPS against 52.0 for Harpoon — about 125% more damage per second. Base hits are Harpoon 25 vs Sandgun 30, so the gap comes as much from attack speed and crit as from raw damage.
Sandgun swings faster at a 16-tick use time versus 30, so it lands on-hit debuffs like ichor, procs set bonuses, and reapplies knockback more often — an edge the flat DPS figure understates.
For crowd control, Harpoon hits with more knockback (6 vs 5), keeping enemies at range while you reposition.
Both are Ranged weapons, so the same armor set and class accessories buff either one — you can swap between them without rebuilding your loadout.
