To holster your weapon in Starfield, simply press and hold the reload button for about half a second. By default, the reload key is "R" on the keyboard for PC players and "X" on the Xbox controller. Holding this button down will make your character put the weapon away. To bring the weapon back out, you can either tap the reload button again or use the shoot or aim buttons. Alternatively, you can use the Quick-Keys menu to select your weapon or item to equip it quickly. This action helps avoid unwanted confrontations in settlements and declutters the screen when the weapon is not needed.
