I recently bought a Luger from Mr. Luger.
The transaction went well, there was some issue with the pistol, looked blue in the picture and green(parkarized?) in hand, so I sent it back under his 3 day inspection/return warranty. I wanted it as it was Weimar unit marked.
Check came back for the purchase price and shipping; but it did cost the shipping back.
His descriptions are minimal, so a phone call is probably in order.
I always chuckle when I read his descriptions, all his Lugers are "mechanically correct"; I have yet to figure out exactly what that means!
