I've purchase bit and pieces of PAPS v4(Pls don't ask me why I rather spent more on shipping to do so) to make up two 18350 & one 18500 mod. The first order I made, all the top cap pin came in copper & I've purchase the Lux pin as extra. Issue is the lux pin don't come with very short silver as the copper pin... My later order of your v4 top cap came in silver pin with the extra very short pin. I found that only the short pin works with AW18350 and the mod I use. Using the long pin would squeeze the switch insulator so much that it fire up. Is there any possibility that you sell the very short silver by itself? I have enough spare for spring and other stuff for the top cap.
