Ejecting only spent casing out of the Revolver

Originally this idea was going to lean into having only the spend casing falling out instead of everything when the revolver is pointed upwards so you don't have to put in 6 rounds every time even if you have just fired one, but I came up with a more cooler and immersive way of doing this.

When the cylinder is open you use the grip button with your off hand to make your character cup the cylinder, having their thumb resting on the live rounds (thumb position will change depending how may rounds are left) while the index finger resting on the ejection rod. While still holding the grip button your press trigger with your off hand that presses the ejecting rod down ejecting the spent casings. then you can reload as normally but don't have to reload the whole gun. Still tipping the gun up slightly but not all the way so you don't need to point at the sky.
