So, I heard back from my source who asked TM directly what's going on with Glocks. TM said there are just production issues in general which are impacting multiple product lines, not just Glocks. TM said there are no issues with licencing and that is a rumour started by a store/distributor that has no involvement with TM and is not to be trusted.
Is TM lying? Possible but doubtful. We'll see I guess.
And I got all that without having to sign a NDA.
In summary, everyone can chill out.
