I'm a realatively new Glocker but from what I understand the US suffix means it was Austrian assembled and imported to US. Now, Im looking at my possible 2nd Glock purchase and the used G22 in question has BKDxxxxUS on lower frame silver tag and BKDxxxx only on slide and barrel. Also Smyrna georgia markings above right side grip on the frame? Is it possible someone came across both matching serial numbers and created a Frankenglock? Please help, I'm so confused !
