I actually restarted a new run with Chemical Pistol for crowd control + Plasma Pistol for damage, about to start Depot A with much smoother gameplay so far, albeit more expensive due to having ammo cost unlike spears (killing Milton who has 2.4k HP for his loot cost 25 acid vials, worth around 35 charons), your suggestion is pretty good, I will try out Electroshock Pistol as well, though from my memory of using it in the past on a Survival Instincts Versatility + Crit Power spec build it was only doing like 1k damage on the first shot with a crafted pistol at around level 18.
