What to know

  • Infinite Pistol is not available in Borderlands 4 – at least from what we can tell.
  • There's an unpatched-yet infinite ammo glitch for Borderlands 4 and it works on all Vault Hunters and nearly any weapon, including underbarrels and ordnance.
  • The glitch relies on a specific Enhancement and an Order-manufacturer weapon with a Ripper underbarrel.
  • When activated, the effect can be transferred to other weapons and lasts for the entire session.

If you’re searching for the Infinity pistol in Borderlands 4, there’s no confirmed drop yet—but a newly discovered infinite ammo glitch lets you experience the same effect on any weapon, making it an exciting alternative.

The infinite ammo glitch in BL4: What exists (so far)

To pull off the glitch, you'll need two specific pieces of equipment:

  • An Order-manufacturer weapon equipped with the Ripper underbarrel, favoring models that are charge-once, full-auto style.
  • The Enhancement called Free Charger, which grants a 30% chance that shots from Order-licensed weapons do not consume ammo when fired from maximum charge.

How to activate infinite ammo in BL4

Step 1

Equip the Order Enhancement “Free Charger,” providing a 30% chance to skip ammo consumption when firing at full charge.

Step 2

Use an Order weapon with a Ripper underbarrel attachment, preferably a model where the magazine only needs to be charged once.

Step 3

Fire and reload the weapon until you notice that the charge-up animation does not trigger upon loading a new magazine.

Step 4

When you spot a shot that does not decrease your ammo counter, quickly swap to any other weapon in your inventory.

Step 5

If the glitch doesn't stick, repeat the process. When successful, you can now shoot indefinitely with any weapon, and the effect will persist for the session

The Infinity Pistol: features and legacy

Infinity Gun in Borderlands 3 (Via: Borderlands Fandom)

The Infinity pistol is a famed Legendary weapon in the Borderlands universe, first appearing in Borderlands 2 and continuing through Borderlands 3. Manufactured by Vladof, this pistol is recognized for never consuming ammunition, no matter how long you hold down the trigger. It fires in a horizontal lemniscate (infinity) pattern, and is designed to be a reliable fallback when low on ammo. While its raw damage is not among the highest, its near-ceaseless rate of fire has cemented it as a fan favorite—especially in tense fights or high-difficulty runs.

Wrap-up: Infinity Pistol vs BL4 Infinite Ammo hopes

While everyone’s eyes are peeled for an infinity-type weapon or a working infinite ammo exploit in Borderlands 4, so far, only the legacy from past games like Borderlands 2 gives us reliable infinite-ammo options (i.e. the Infinity pistol). If you’re hoping for infinite shots in BL4, keep tabs on community reports, patch notes, and mod/skill synergies — but don’t count on anything working until validated.
