Drowning in loot on Kairos? Borderlands 4’s generous enemy drops can quickly overwhelm your limited inventory space, forcing tough decisions about what to keep and what to discard. While the game doesn’t make it obvious how to drop items, mastering this essential skill – along with smart inventory management – will keep you looting efficiently without missing out on valuable gear.
Here’s your complete guide to dropping items, managing inventory space, and maximizing your loot potential in Borderlands 4.
How to Drop Items: Platform-Specific Controls
The game doesn’t clearly explain how to drop items, but once you know the controls, it’s straightforward. Here’s how to drop items from your inventory on every platform:
PC (Keyboard & Mouse)
- Open your inventory
- Highlight the item you want to drop
- Press and hold the “R” key until the item drops
Xbox (Controller)
- Open your inventory
- Select the item you want to drop
- Press and hold the “Y” button until the item drops
PlayStation (Controller)
- Open your inventory
- Select the item you want to drop
- Press and hold the “Triangle” button until the item drops
Pro tip: The hold duration prevents accidental drops, so make sure you hold the button long enough for the action to complete.

Alternative: Using the Swap Function
Before dropping items outright, consider using the swap function for equipped weapons:
How Swapping Works:
- Pick up a new weapon while your inventory is full
- The game prompts you to swap with your currently equipped weapon
- Your old weapon drops to the ground automatically
- Your new weapon becomes equipped immediately
When Swapping is Useful:
- Quick weapon upgrades during intense combat
- Field testing new weapons without inventory juggling
- Emergency situations where you need better gear immediately
This method is faster than opening your inventory during combat, making it perfect for those heated firefights where every second counts.

Smart Inventory Management: Better Than Dropping
While knowing how to drop items is essential, dropping should be your last resort. Borderlands 4 offers much better alternatives that can actually benefit your progression:
Selling Items for Profit (Recommended Method)
The Junk System:
Borderlands 4 includes a brilliant “Junk” marking system that streamlines selling unwanted loot:
Step-by-Step Process:
- Open your inventory regularly (after each major fight)
- Mark unwanted items as “Junk” using the designated button
- Head to any vending machine in safe areas
- Press the “Sell All Junk” option for instant cash
Why Selling is Superior to Dropping:
- Immediate cash flow for purchasing better gear
- No wasted loot value – everything has monetary worth
- Supports upgrade purchases from vending machines
- Funds ammo and health restocking
What to Mark as Junk:
- Lower-level weapons that you’ve outgrown
- Duplicate gear with worse stats
- Weapons that don’t match your build or playstyle
- Common/uncommon items when you have rare alternatives

Using Banks for Long-Term Storage
Bank Storage Benefits:
- Preserve valuable gear for future characters
- Store situational weapons for specific encounters
- Keep legendary items even when inventory is full
- Share items between different Vault Hunters
Strategic Banking:
Items Worth Banking:
- Legendary weapons with unique effects
- High-level gear for future use
- Situational equipment (specific elemental weapons)
- Collectible items with sentimental value
Items to Avoid Banking:
- Common weapons easily replaced
- Severely underleveled gear that won’t remain useful
- Broken or damaged equipment
- Items you’ll never realistically use

Advanced Inventory Management Strategies
The 80/20 Rule:
Keep your inventory roughly 80% full during normal gameplay. This provides:

Elemental Weapon Management:
Maintain at least one weapon of each damage type:
- Incendiary for flesh enemies
- Shock for shields and robots
- Corrosive for armor
- Cryo for crowd control
- Kinetic for general use
Build-Specific Organization:
Organize inventory around your chosen specialization build:
- Weapon types that complement your skills
- Class mods that enhance your playstyle
- Grenades/ordnance that synergize with abilities
- Shields appropriate for your combat role

When inventory fills during intense combat:

- Drop ammo-hungry weapons when ammunition is limited
- Prioritize mission-critical items over personal preferences
Optimizing for Different Game Modes
Solo Play Inventory Strategy:
