Lloyd, Are you rich or insane? Shooting a 1915 Artillery....Well, since you have a lot of money I will make this suggestion; I don't believe you can adjust the sights enough to compensate for a nine inch adjustment at 25 yards. They just won't move that far over. You need a tool to move the sights unless you are quite the machinist. There are two incredibly small pins inserted into a small diameter rod that make this tool. They are fragile too since they are so small and you can easily break the tool by trying to crank over a sight that has come to a stop. They are often seen on eBay or I am sure you can buy one from Ralph, Randy Bessler, or Bob Simpson or maybe Tom Heller.
If you want a good shooter LP-08 you could easily trade for one and have some spare change left over and preserve this fine example for posterity but I am not sure it is wise to run a caseload of ammunition through that 1915 pistol. It's a purty one! Hate to see it broken...Jerry Burney
