Is getting a perfect parry and not getting a gun strike supposed to be a thing? 

Because I made about six or more perfect parries in a row against some tyranids and got nothing. 

I do realize you don't get a perfect parry/ gun strike against the first/ second swing of a combo. Not talking about that. 

Is this just ANOTHER bug that's crept its way in? 

This was with Sniper.

I've also noticed recently that the parry and auto scan on Tactical isn't working all the time either, now that I think about it.

No. Heavy bolt pistol. 

It's just weirdly streaky.  It'll work fine for a while, then you won't get any gun strikes for a while, then it'll work again. 🤷‍♂️

It might be intentional to control us from doing gun strike after gun strike after gun strike, but if that's the case it'd be nice if they come out and say it. 

I think it's a bug though, since other "trigger on perfect parry" things also aren't working all the time.
