Thats a very interesting suggestion...to pick up a Receiver with 6" barrel and just swap them out.........being very new to Luger Collectiing......I appreciate any suggestions as to where and how to obtain a Receiver with barrel......also could anyone give me a "ballpark" figure on what something like could run..??......and as I said.....maybe point me to someone known to the board that sells parts......I appreciate anyone taking the time to answer......Best Regards......Hans Fischer
