I was in a local gunshop and found a commercial 1917 45 Hand Ejector. I came home and read up on the 1917 in the Standard Catalog. How rare are the commercial 1917s and what would be an estimated value? The asking price was 550.00 and I would rate the condition at 70%. It had bluing wear on the back strap and had what appeared to be a police department's name engraved in it. The bore looked good and the lockup was tight. Thanks for any help!
