Title says it, I'm playing a tech specialist with the second shot perk and it works fine except w/ tease and psionic ranged weapons.
I've tested with Heavy Slut Ray (psionic), Slut Ray (psionic) and the Goovolver (tease) (none of which fires twice).
Myr Venom Thrower (drug) works fine, so it's not lust weapon specific.
Here's 3 screenshots from the same fight showing this (notice how its only the last one that fires twice):
