Are you scratching your head because you can’t seem to unlock more weapon slots in The Outer Worlds 2? It’s not just weapons, mind you. The types of grenades and medical inhalers that you can equip at any given time tend to be very limited as well.
How to unlock more Outer Worlds 2 equipment slots
There are a couple of ways to unlock additional item slots in the game:
- One option is to socket mods that grant an extra slot. Note that this effect remains active as long as you have that gear piece equipped.
- Another option is to choose the right perks. Note that this effect is permanent.
Armor mods that grant bonus equipment slots
If you want to unlock more weapon slots in The Outer Worlds 2, as well as slots for your grenades and inhalers, then you could opt to find the following mods:
- Extra Holster – Gain an additional weapon slot.
- Grenade Bandolier – Gain an additional grenade slot.
- Extra Primer Port – Gain an additional medical inhaler slot.
These items are normally sold by vendors in settlements. Alternatively, you might be able to loot them from certain enemies or containers.

How to apply armor mods
Once you have a mod, you can attach it to a valid helmet/headgear by interacting with a workbench. Select the Mods menu, then choose an option that you’d like to socket to a helmet. Just remember a couple of caveats:
- Any mod that you attach to an item cannot be removed. Any new mod that you apply will destroy the previous one.
- If you switch to a different helmet that doesn’t have the necessary mod, you’ll lose the effect and the extra slot.

Perks that grant bonus equipment slots
If you want a more permanent solution to this issue, then you can select the right perks:
- Commando:
- Grants an additional weapon slot.
- Requires Melee 1 or Guns 1.
- Grenadier:
- Grants an additional throwable item slot. Also grants +10% explosives damage.
- Requires Explosives 2.
- Pharm-Thusiast:
- Grants an additional primer slot, allowing you to gain the effects of multiple primers at once.
- The total toxicity of all primers used simultaneously will be combined upon activation.
- -25% toxicity received from inhalers.
- Requires Medical 2.
