For the Grineer units, see Regulator.

The Regulators are MesaIcon272.png Mesa and MesaPrimeIcon272.png Mesa Prime's signature Exalted Weapon, which are used when her Peacemaker130xDark.png Peacemaker ability is activated. Unlike other ranged weapons, the rapid-firing Regulators will automatically target and shoot at enemies within a large aiming circle directed by the player, removing the need for precise aim.

Refer to the weapon's ability page for a list of mods that affect the weapon.


This weapon deals primarily DmgImpactSmall64.png Impact damage.




  • The Regulators appear in the Arsenal after unlocking Mesa's Peacemaker130xDark.png Peacemaker ability.
  • The displayed damage number of 125 in the Arsenal is the Regulators' base damage of 50 boosted by Peacemaker's innate +150% damage bonus.
    • This damage bonus is affected by Ability Strength.
    • When in the Simulacrum, the arsenal display may be glitched and instead show the Regulators' damage without the multiplier.
  • The ammunition related statistics displayed (such as magazine size, ammunition pool and reload speed) are merely a technical formality of the stat preview screen as the weapon actually consumes 0 bullets per shot, thus allowing infinite ammo economy.
  • As an Exalted Weapon, this weapon comes with an Orokin Catalyst.png Orokin Catalyst pre-installed.


  • The name of the Regulators might be a reference to the Regulators, a posse from the American Old West said to have been co-founded by Billy The Kid.
  • Before the introduction of modable Exalted Weapons, the stats of Regulators were affected by the mods equipped on the player's Secondary weapon.
  • Regulators have an alternate skin available for them in the form of the Regulators Presidio Skin that players can equip if they own the Mesa Presidio Skin.
    • The Regulators Presidio Skin can be equipped regardless of whether or not the Mesa Presidio Skin is equipped.
  • On MesaPrimeIcon272.png Mesa Prime, the pistols are named Regulators Prime. Their stats are, however, identical to Regulators.
