To cancel doubt when trying to get this to good to be true deal, ask for a 5 second WhatsApp vid of the seller weighing the weight. That, with detailed pics should help.
Thanks again for the assistance.
I have gone ahead with the purchase. Hopefully, it proves to be authentic and it fits my USP9 without the problems others have experienced with fakes and poor alignment issues, etc.
They certainly look cool!
The seller claims it is all steel and for a 9/40 USP. I guess I will know for sure when it arrives.
