Hello,
I got the SureFire King mod a few weeks ago and I haven't had this problem until today. I have the Sony 18650 1600 mAh battery and I recently bought the Sony VTC4. Now when I adjust the secondary pin on the mod it fires without using the button, because the bottom is slightly raised so that it contacts the firing pin. I'm not sure if there's any way to fix this but the Sony VTC4 works. It also works if I leave a gap between the battery and top pin but then there's battery rattle.
