I suspect that the button may be prone to melting with a stock firing pin and spring when running sub 1 ohm builds and repeatedly press fire for extended durations?
I noticed it on one of my grands (slight melt). This is when I got 27 ga and built a .8 ohm coil and started to use the mod to fire / squeeze coils. I originally did it for an extended duration but have since learned to fire the coil only until it glows before squeezing it with pliers, not fire it for like 10 seconds, squeeze like 5 times in succession.
I really have no way to prove this theory because I'm running 1.5 ohms, 28 ga, fuse mod and rarely fire for longer than 3-4 seconds. My buttons are flawless and I get no arcing.
