New to ECF, not new to vaping

Was gonna post this as 1 of my 5 "initiation" posts before I can post elsewhere, but I've actually got a question that I need answered and maybe someone around here has had the same issue, and fixed it, or knows where I'm going wrong.
So. Little background. I did all my homework, spent weeks researching mechanical mods and sub ohming before I gave it a shot. Learned all about ohms law, what batteries to get, what batteries not to get, etc. I'll talk about my set up, then my problem.
Got my Igo - W RDA, dual coil, reading at about .4 ohms. I'm using the green sony 18650 vtc4 high drain batteries that have a 30a limit. And it's in my caravela mech mod.
Theoretically, I should be fine. A fully charged battery putting 3.7v to an RDA measuring .4 ohms only produces 9.25amps, well under the 30 amp continuous that my battery is rated at.
So here's my problem, it just started happening and I'm a bit concerned. Or at least I just started noticing it. It seems like whenever I'm firing my mod, the firing pin is heating up as well. Not like, oh .... that's hot, but also not just a little warm.
I can't figure out why either. I regularly disassemble and clean my mod thoroughly too. It doesn't matter if the battery is fully charged or if it's starting to die, the firing pin gets hot. And it does it with both of my batteries, I have two of the sony ones. I don't see anywhere that I'd be shorting out either. I'd attach some pictures but I don't know how..

I have had this issue but not with a caravela, mine was with a Valkyrie. With my setup it was happening because the pin wasn't making a good enough connection with the negative terminal of the battery, with running such a low ohm build more current is being drawn to your atty. check if the pin has any high spots that are only allowing a small portion of it to connect to your terminal, don't know much about the caravela but is the pin protruding past any delrin insulator enough? try noahlox on the threads to bridge any weak connections, have you tried other brands of batteries, is the wrapper on the batteries covering too much of the end where the pin connects? just a few thoughts.

I'm not into sub ohming so I'm probably not much help.Do you have another topper besides the Igo? Or another mod besides the Caravela?

Oh yes, Welcome to ECF.

Nope, only got the igo for the rda and only got my caravela for mech mod.
I have a provari but it will only fire if the resistance reads 1.0 ohms or higher. So it doesn't do me much good for my igo build.

Hi and Welcome to ECF

I only wanted to add when calculating Amps - use 4.2 V - that is your fully charged battery voltage. And good on ya for understanding what you are doing And HOW to do it!

( I do go 0.7-0.8 but not down to the world of 0.4 - and I use a bottom feeder- so Im not certain if the warm part is entirely normal at 0.4 in a caravela or a bad thing- but I fully agree with checking connections and Noalox)
