Yeah, but I'm pretty careful about that. Very careful, actually. Probably inordinately careful, truth be told.
My guess is it's mostly from the coil sputtering after I've released the firing button. I've never been very careful about continuing to draw after I've released the button. I think it's a little worse with contact coils - which makes sense to me.
Just to be clear, the amount of leakage I'm usually getting is IMO manageable. Takes only a couple of minutes every so often to clear it out and it's not like it's a terrible mess. I've had it leak onto my mod only once, but that was when I first discovered the issue, I had been using the unit for quite awhile and some user error during a fill was probably involved.
