@PepNYC ,can you upload a photo of these parts? I want to be sure I'm doing it right...

Thanks
Sure but it might take a while. I'm at work and can't do it right now.
In the meantime here's a brief description of what I did.
1. Take off the bottom cap.
2. Get a pair of needle nose pliers and just grab on the the piece inside that touches against the center post when you press the fire button.
3. Unscrew. Be careful not to lose the little spring that will pop out when you unscrew it.
4. LIGHTLY sand the end of the little screw on piece that touches the center post with a very fine grit sandpaper. All you want to do it remove the top silver layer or chrome coating so the brass is visible. I think I used a 2000 grit sandpaper.
5. Do the same for the center post under the spring that connected to the bottom cap.
6. Once you can see the brass on both parts, just reassemble. The tricky part is getting that little screw piece back on with the tiny spring in it while you screw in the fire button.
Did I mention sand lightly?

If you sand that little screw on piece too much you'll basically ruin your
mod because it won't touch the center post. Be careful, take your time, sand lightly and just pay attention to how it comes apart. You'll do fine. I'll try to get some pics up later on.
