A quick question, I'm a Lex main (I played on Old Lex and I actually hit my shots instead of just auto-aiming, don't hate) and I noticed that his Eroded Oath pistols are apparently "available in the Mixer Store," yet when I went to check the Mixer Store, they were not there. Is this a bug or are they actually available a different way, like the Mixer Khan is a quest reward item.
I'm wondering because I don't want to spend a ton of time on Mixer only to not get anything worthwhile.

Thanks y'all
