Glad I found this thread. I'm a huge sucker who falls for the "1 of X produced" far too often, and I had rose tinted glasses on so bad that I still have thorns in my eyes and I missed some of the glaring issues with this. Placed an order around an hour ago and have already requested a refund. I mean it would be cool to own, and the current price ($2900) is a lot better than the original 5-6k at the begining of the thread, but it was a panic buy that I really can't justify just to LARP around with. I also was unaware that there's no A5 version of the 320.
Very deceptive marketing currently, since the manufacturer is still not listed in the title, nor is clone mentioned. The description sounds like it's a genuine HK item with a limited run in 37mm, up until you get to the tiny part tucked away saying it's that KaleKallip, which is easy to miss when you are a buyer in full on FOMO mode.
My personal opinion is the previous listings they had were outright fraudulent, and they've done the bare minimum to create plausible deniability since they are still not being very forthright with what they are selling.
Edit* they cancelled my order. I mentioned the title should include clone or the actual MFG name and not have it hidden at the bottom of the description and they had the audacity to act like it's super obvious this isn't a real HK and that they don't mention HK anywhere in the listing (peep second sentence of the description). Not only that the "bottom" of the description is in the middle of a wall of text... it's the bare minimum transparency to have plausible deniability, but there's very little attempt to be upfront about what this item really is. Also, i brought up the nomenclature being that of HKs and with no clear MFG in the title, its suggestive of being HK, and they said the nomenclature is of CAPCO For the US military. The launchers the US army have are HK and are marked HK as far as I'm aware, from my sample size of one I've gotten to experience, so I dont find that comment convincing at all.
Disappointing experience since I've had decent interactions with them in the past.
