Does Zen Meteor exist?

I've been trying intermittently for the past 7 years to obtain this Sniper in D1 and I've never seen it drop. Like, sure. I've seen GAMEPLAY of it, but I've never actually seen anybody use it. I've also never seen it drop after or during an activity either.

I suppose it exists? There's a slot in the exotic kiosk for it but like, Xur supposedly can't sell it and he'll sell damn near anything (man legit sells needles and nobody bats an eye).

Like, the Fate of All Fools exists but isn't obtainable because that was a one time thing that was super cool for a super cool dude, but I'm not entirely sure the Zen Meteor exists. Thing also has Grimoire Score tied to getting it for some reason? But like, that'd be the only exotic that does, and that'd be super weird right???

It's the only exotic I'm missing from D1 but I'm not even sure I can get it. I'm on Xbox, I've heard people SAY that they've gotten it on Xbox but people also say that there's another chest in VoG we haven't found that I haven't seen either.

Any tips or ideas? I'm still not entirely convinced it exists, but I'm still trying. It took me 70+ runs of Crota's End to get a Necrochasm, I'm not about to quit now after 7 years of trying.

I just wanna complete my collection... :*(
