Well I can't unscrew the center pin at all or else it would give me that ugly gap with the switch like the first picture. I did everything you said and this is the result.

There is still ALOT of space when the switch is fully screwed in with the center pin also fully screwed in. It is sort of hard to pinky fire the switch since it still crunches and gets caught.

Travis, you have two problems... the heat and the crunchy switch. It seems you have beat the heat, so time to work on the switch. I have a Nemi clone also and had some crunching in the switch. So I took the switch apart and lightly sander the outside of the post the switch travels on (the post that the small locating pin fits in), and also sanded the inside of the brass screw in part that rides on that post. I also used some dielectric grease (any auto parts or hardware store carries small tubes for a couple bucks and it's made for electric applications) and the switch was smooth at any angle of hitting the switch. Don't get any grease on the silver plated pin that contacts the battery or the inside of the post that the silver plated pin screws into. My switch was buttery smooth after that. 10 minute job.
Also be aware that the depth of your 510 connector on you atty will affect how far out your switch will be screwed. If you have an atty with a shorter 510 connector you will have to screw in the 510 adjustment pin of the Nemi more, which means you screw in the battery end cap more and may put that switch in a better position to the outside of the bottom tube the switch screws onto. My Trident had a very long 510 connector that I wound up sanding down a bit because the switch didn't feel as good with the switch out farther. My IGO's, Nautilus, and Russian had shorter 510's and were fine. It was still very smooth after sanding and greasing, but it took more pressure when the button was pressed from the side with the Trident before shortening the 510.
Finally, I got the magnetic switch kit from FatDaddyVapes and he also has a different set of silver plated contact pins to allow 1mm throw with the kick extension instead of the normal 2.5mm throw. His magnets are much better (and stronger) that the FT magnets. It was $14 for both sets. I really like them. Didn't make the switch any smoother, it was already smooth, but I like the shorter throw. It just feels better.
