It is all about the economics. In the "sand box" a glock costs close to 4000 US$. That is why there are so many local copies of various pistols, especially TTs...and they are cheap but that is what you get for the money. I wont even consider to rate these copies as they are pure JUNK!
I would like to see a hypothetical market survey of sales of Glock in the US if the consumer had to pay 4000$ for it.
