mesinge, in my country Glock is a very popular weapon (just like in the US), it's not so hard to get a handgun permit and models 28 and 25 are legal to own from private citizens. Yet try to guess, how many 28 & 25 were sold for the last 5 years... Zero. In your country, even if it's legal to own such Glock, except for very few people, nobody would buy it. On top of that this topic is discussed via the Internet numerous times - the OP just has to type "Glock+28+US" in Google...

P.S. Actually, there is a way to own Glock 28 (25) in the US - just Google it...
