Jim et al, I agree with the comments above, but seriously doubt that any of the bead front sight were ever installed at the factory (except on the Luger carbines). These were probably available as an option from some of the US importer (Stoeger, Pacific Arms, etc) as they would also install new barrels in either 7.65 or 9mm in lengths from 4" to 22". I do have both used and new original Luger front sight blades in stock in the $15 to $25 range but some fitting may be required. Lugerdoc at
