I used a piece of non-resistance wire, wrapped it around the spring and stuffed it under the lip that the button pushes up against when pressed all the way down. I was finding that I would get misfires or shocks unless I made sure to push the firing button to the side. I don't know the engineering on why it works, maybe because the NR wire helps to conduct current to the tube body to complete the connection.

michiu, i've seen your fix before and i'm not sure what NR wire is. That's not kanthal or nicochrome is it? is it house wiring? we have plenty of that in the garage from remodeling our 100 yr old house. I also have some enamel coated magnetic wire from radio shack that i bought to mod several years ago.
would any of these work? I wish the spring was designed to actually seat in the button so it doesn't move all over the place when you screw the button on. Kinda like the puresmoker legacy had in it's first design.
so no hot button or shocks after using your wire fix? i found when i push the button longer, that's when i get hot button now after my other adjustments. i have COPD so i take short drags and usually hit the button several times per drag, but this morning i held it longer, because i don't want to wear the button out, and that's when i got hot button again. I've also had hot button on my P18 at times, but that's usually a short somewhere. I'm afraid of shorts lol
very strange design by Sig. it looks beefy which is what attracted me to the device, and being stainless, because i drop stuff all the time, but the shocks and hot button are a pita. sometimes i can feel the button pulsing when i push it too. i don't know if that's the sig K volt board i'm using in it, the neuropathy in my hands, or something else.
thank you so much guys for all your help. i ask a lot of questions i know ;-)
