Not sure if they count as "Weapons," but every plasmid from Bioshock other than the Electric Shock one. Shock enemy to stun, shoot in face. No need to ever equip anything else.
Even the developer seemed to realize this. As you get into the later parts of the game, Thuggish Splicers (the melee ones) gain immunity to being stunned by it. Luckily they never gain immunity to a crossbow bolt to the face.
