To make your weapon appear on the side in MM2, you usually need the Radio gamepass/effect; that’s the common way players set a side-holster look instead of the default back placement. In gameplay, you can still equip a knife or gun from your inventory/hotbar by selecting it, but the side placement itself is tied to that cosmetic setup rather than the basic equip action.

Quick Scoop

  1. Open your MM2 inventory or loadout.
  2. Equip the weapon you want to use.
  3. If you want it shown on your side, get and enable the Radio option/gamepass.
  4. Rejoin or re-equip if the placement doesn’t update right away.

What people mean by “sign”

In MM2 chats, “sign” is often used loosely, but for weapons people usually mean showing or equipping the item, not literally writing on it. The side placement is a cosmetic effect, while the actual weapon use still works the normal way once equipped.

Notes

  • This does not change weapon stats.
  • It is mostly a visual preference.
  • The exact buttons can differ a bit on PC and mobile, but the idea is the same: select the item from your inventory/hotbar.

If you meant a different “sign” feature in MM2, the most likely answer is still the Radio side-placement setup, since that’s what players usually ask about.
