Hello Powdercrank,
Let me say that the Artillery rear sight is a beautiful item. You mention about rear sights of 1917 Artillery so maybe you do not see the screw used to increase the accuracy when used for long-range shooting.
According to the LP08 manual, this beautiful pistol was effective against â??head-sizeâ? target at a distance of 600 meters.
Starting from the 1917 the rear screw is no longer implemented.
If you want to have further information about the LP08 history you can have a look at my web site where an article is available that quickly describes the history of this beautiful pistol.
Ciao
Mauro
