So it shows "no atty"... and, it won't fire, right? You don't say what attys... but if they have an adjustable 510 positive pin (like a
kayfun), or a pressed in (to a rubber seal) coil tail retention pin (like most Kanger clearos for example), you can adjust - or carefully pull the retention pin down to see if your issue is a simple gap between atty and
mod positive pins.

innokin APVs in general have an issue with too deep a 510 pin. I can go into detail with average measured depths and so on, but your 510/510 adapter is, sadly, for now, a common fix. Innokin engineering and CS departments are well aware, and will have a shorter pin depth (if not already) by the first of the year.
A more permanent (and attractive fix) is to machine or file the 510 collar down about .010" -.015". (the beauty ring too) ;-)
