First auto-fire...

[Huh?!]

When I started to get into mech mods, I knew about the possibility of auto-firing. But, my thought process was "it won't happen to me. I'm OCD and I always lock the button." Well, only took three weeks into my mechanical life to have it happen in my pocket. Long story short, threw my mod in my pocket to chase after my son. Forgot about it. a few minutes after sitting down my only thought was "why the eff is my pocket so hot...." Ugh.

I don't use a mech mod very often, so all I can offer there is be careful, Bud.
I never carry any of my APVs in my pocket. I use either a mini flashlight holder or a cell phone holder attached to my belt.
The flashlight holder is for tube mods and the cell phone holder is for box mods. I've never had a problem using either.

Best advise I can give is anytime you feel a mech getting overhot, in pocket or while vaping, drop the battery out immediately!
Then you have time to figure out what's up. If it's just the lock ring cool, if not at least it can't continue.
When chain vaping sub-ohm occasionally I'll drop a battery to see if it's getting hot when the mod or button is warm, better safe than sorry and it's not like it's hard.

It happens to everyone at least once. It even happened to me with a recessed fire button. Insatiable it down on a porch step and there was a little stone that was dead center on the button and just enough to get it to fire. Luckily I caught it in time and was able to drop the battery out.

 

[Huh?!]

First thing I did was drop the battery. Then I disassembled the whole thing to make sure no scoring. I was lucky as well in that I caught it fairly quickly.
