From what I seen, they are getting more and more expensive. It depends on who the importaer/manufacturer is. I looked into one as a tiny carry gun a while back, and saw a few I should have pounced on at or around $400.
I seen them for around $600 regularly now, some $575 some $625, some more (700-800?) if they are german manufacture and old.
The interarms imported ones are generally the ones that people know are good. the Modern smith and wesson ones people dont like.
