What buttons do you need to press to buy a gun in call of duty?

To buy a gun in Call of Duty, first navigate to the buy station in the game. Use the appropriate button to open the buy menu (typically the "Interact" button, often mapped to the "Square" on PlayStation or "X" on Xbox). Then, select the weapon category and choose the specific gun you want to purchase, confirming your selection with the designated button (usually "X" or "A"). Ensure you have enough in-game currency to complete the purchase.
