how to change hot barr guns in roblox bloxfruits

In Blox Fruits, you usually change the gun slot by rearranging your hotbar or inventory , not by “changing the gun” itself. On PC, open the inventory/hotbar with the tilde key ~, then move the weapon to the slot you want; on mobile, use the button beside the hotbar, and on Xbox the inventory controls are shown after opening it with the three-line menu.

What to do

• Open your inventory/hotbar.

• Move the gun to the slot you want, such as slot 4 instead of slot 3.

• If it does not stay where you want, try unequipping and re-equipping the weapons in the order you prefer.

Why it matters

Players often place swords and guns in specific slots for PvP timing and muscle memory, and some community posts mention keeping guns in slot 4 while swords sit earlier in the bar.

Extra note

If you meant upgrading a gun rather than changing its slot, Blox Fruits weapons are upgraded through the Blacksmith, including guns and swords.

TL;DR: Open the inventory/hotbar and drag the gun into the slot you want; if you meant upgrading the gun, go to the Blacksmith.
