The brass buttons were delivered to me this week, they look AWESOME! They feel very high quality and have a different click sound from the stainless steel ones.

It has the same thread size as the other Convoy buttons, so it should fit any flashlights that have a swappable button, in this case I used the lighted plastic base of the metal button that is sold for the S2+

It looks like the brass circle where you click is a bit smaller than on the SS one, letting more light pass through the silicone around it and creating a bigger inner circle of light.

My brass S2+ looks perfect with this new brass button.
