Yes, they have very sensitive positive pins, even the authentics. Mine does best fully tightened and on a
mod with an adjustable pin. Its not keen on spring loaded 510s either, but settles down after a minute. The only other solution is to make it a delrin insulator that prevents the pin from touching the 510 opening. You can add a second 2 x 1 o ring to the pin, but that will only work temporarily.
