I took Sheepherder's advice above and gave Simpson LTD a call after browsing their website. Talked to LeRoy (Salesman) and he pulled a few Lugers, then got Robert (Bob?) (Owner?) on the phone with me... Robert went over each pistol and helped me select one. He was very patient and answered my Luger Newbie questions.
Pistol came yesterday, I'm well pleased
Selected a 1916 DWM Police rework, 9MM. All matching except for the magazine.
And now more learning begins !
