Heavy in the hand with a bone-crushing kickback. This Prime version of this shotgun adds remote detonation of the weapon's airburst round.

The Corinth Prime is the primed variant of the TnHeavyShotgun.png Corinth shotgun with improved status chance, magazine size, buckshot fire rate, and air burst damage and explosion radius. The air burst no longer has a set range before exploding allowing it to damage enemies from farther away, but in turn no longer has a delayed fuse and must be manually detonated with Alternate Fire. Instead of individual rounds, the weapon reloads the entire magazine at once with a slower reload speed. Corinth Prime was released alongside TitaniaPrimeIcon272.png Titania Prime and PangolinPrime.png Pangolin Prime.


This weapon deals primarily DmgPunctureSmall64.png Puncture damage on its primary fire and DmgBlastSmall64.png Blast damage on its alt-fire.


  • Primary Fire shoots a wide-spread, close-ranged buckshot:
  • Alternate Fire launches a grenade that creates a 9.8 meter area of effect explosion after remotely detonated with Alternate Fire.
    • Physical contact with the grenade has a guaranteed DmgImpactSmall64.png Impact proc.
    • High DmgBlastSmall64.png Blast damage – effective against Machinery and Fossilized.
    • Explosion does not need direct line of sight to deal damage and will penetrate walls.
    • Tied with Cedo.png Cedo's alt fire and Trumna.png Trumna's alt fire for the second highest status chance of all primary launchers, behind Bubonico.png Bubonico's alt fire.
  • Large magazine size.
  • Innate two Madurai Pol.svg and one Naramon Pol.svg polarities.


  • Primary Fire:
    • Has linear damage falloff from 100% to 33% from 18m to 36m target distance (distances are affected by Projectile Speed).
  • Alternate Fire:
    • Innate DmgBlastSmall64.png Blast damage – less effective against Ferrite Armor and Infested Sinew.
      • Physical contact with the grenade deals lower DmgImpactSmall64.png Impact damage.
      • Damage cannot be increased with DmgPunctureSmall64.png Puncture or DmgSlashSmall64.png Slash mods.
        • The physical contact grenade deals only DmgImpactSmall64.png Impact damage, while explosion itself deals only DmgBlastSmall64.png Blast damage, therefore the explosion does not benefit from any physical damage mods.
    • Grenade only explodes in midair; does not explode if it hits a surface or an enemy.
    • Grenades have travel time, heavy arcing, and needs to be manually detonated.
      • A grenade hitting an enemy without exploding causes much less damage compared to the explosion.
    • Extremely low critical chance.
    • Low critical multiplier.
    • Explosion inflicts self-stagger.
      • Manual detonation should prevent accidental self-stagger unless mistiming or rapidly moving towards the grenade's impact area before it explodes.
    • Explosion has linear damage falloff from 100% to 10% from central impact.
    • Consumes 4 ammunition per shot.
  • Slow reload speed.


  • Corinth Prime (Buckshot), compared to Corinth (Buckshot):
    • Higher base status chance (9% vs. 6%)
    • Higher burst DPS (1,180.87 vs. 972.97)
    • Higher sustained DPS (973.51 vs. 632.54)
    • Higher fire rate (1.42 round(s)/sec vs. 1.17 round(s)/sec)
    • Larger magazine (20 round(s) vs. 5 round(s))
    • Smaller max ammo capacity (120 round(s) vs. 132 round(s))
    • Slower reload time (3 s vs. 2.3 s)
    • Different polarities (Madurai Pol.svgMadurai Pol.svgNaramon Pol.svg vs. Madurai Pol.svgMadurai Pol.svg)
    • Higher Mastery Rank required (14 vs. 8)
    • Lower disposition (0.9 vs. 1.15)
    • Air Burst Explosion:
      • Higher base damage (2200.0 vs. 404.0)
      • Higher status chance (50% vs. 28%)
      • Lower fire rate (0.667 vs. 1.17)
      • Larger range (9.8m vs. 9.4m)

  • The Air Burst is fired using Alternate Fire, and then manually detonated with Alternate Fire again. It will not explode if hitting a surface, an enemy or a corpse.
  • Modding the Corinth Prime with Punch Through does not allow the grenades to pass through enemies or objects.
  • The grenade does explode on its own, but only after traveling about 90 meters in its 2 second lifespan. Improving Projectile Speed will increase the distance it will travel before exploding on its own and vice versa if flight speed is reduced the grenade will explode closer to the player.
    • Reducing flight speed will also decrease the minimum and maximum ranges in which falloff occurs on the normal fire, which is not recommended.
  • Corinth Prime has a different reload animation, unlike its regular counterpart. In this case, similar to reloading a magazine in general.
    • Because Corinth Prime has slower reload speed than its regular counterpart, equipping a skin may result in sluggish reload animation on their respective skin.


  • While direct hits from the Alternate Fire deal significantly reduced damage, the guaranteed DmgImpactSmall64.png Impact proc can be used to momentarily stun a priority target, allowing for a follow-up shot.
  • An efficient way of using the weapon's Alternate Fire is by detonating it slightly overhead enemies. Not only does aiming overhead reduce the chance of the shells prematurely hitting anything and wasting potentially powerful crowd control, the resulting explosion can also trigger headshots dealing far more damage within the blast radius.
  • IvaraIcon272.png Ivara's Navigator130xDark.png Navigator halves the distance that the grenade has to travel before an explosion.
  • The sound of the pump action when chambering the last shell in the magazine is noticeably different, providing an audible warning that reloading will be required.
  • The Corinth's alt-fire can effectively set up enemies for finishers. This makes it useful when accompanied by any melee weapon with Mod TT 20px.png Finishing Touch.


  • The barrel is shaped like a Void Key.
  • The weapons is famously featured during the TennoCon/2021 in-game playthrough of the opening of The New War, when the Grineer soldier Kahl-175 plucked the gun off a fallen RhinoIcon272.png Rhino to fend off Sentient enemies at the final leg of his playthrough.
