Just to let you know I have changed the location of the three triad red dots on Lugers reworked/restored by TLSS, they have moved from the bottom of the stock lug to the inside of the magazine well. You have to REMOVE the mag to see them. Some early Lugers, as you may know have NO STOCK LUG, hence I needed another location to place the dots, it is pretty much standardized now. They are located on the underside of the semicircle on the frame that is relieved to accomodate the circle of the magazine bottom. Thor
