A clever user on BARFCOM came up with the link to a patent on the new HK pistol.
That’s right, real actual “breaking” news in GD for once! As soon as I heard about a new “big announcement” from HK I did some sleuthing. Found a patent just issued for a new handgun couple weeks ago. Remember you heard about it here first: https://uspto.report/patent/grant/D918,328#D00000
The patent was just issued on May 4 2021. Patent applications aren’t publicly available until 18 months after submission or after issuance.
