    I received a boresight today for my 9mm pistol. It appears that my pistol is sighted dead on at 3 yards but at 10 yards, the sights are about 1-2 inches low.

    I do not have adjustable sights on my P-01 so how (if at all) can I adjust the sights so that I am on at 10 yards?

    thanks

    Do you have a file? :D You need a higher rear sight or a shorter front sight. Not familiar with that model, but different height sights may be available. That's assuming it's not the shooter of course.

    Thank you; I'm curious if it is a normal phenomenon for the sights to be dead on at very close range and then for the poa to move steadily upward as you move farther away----is this normal?

    Have you actually shot it yet?

    Plenty; I have about 800 rounds fired; just decided to get a boresight for several of my handguns to see just how accurate the sights are.

    I had no idea about the movement of the POA until I put the boresight in.

    As well it should be.

    Sorry to tell you this now, but you wasted your money buying it.
    You cannot laser bore sight a handgun.

    Handguns move and recoil upward, and twist in the hand whichever way the rifling twist is starting the bullet spinning 50,000+ RPM in the barrel length.
    While the bullet is still in the barrel.

    Where it points with a laser bore-sighter, and where it hits when hand held under recoil are two different things.

    And never the twain shall meet!

    See this about that:
    Revolvers kick off target more then autos.
    But they all kick up off target, and start to twist in the hand while the bullet is still in the barrel.

    As an aside.

    Now that you have paid good money for it?

    Sight the gun in at 25 yards by shooting it as you normally should do.

    Then see where the laser dot points with that sight setting.

    Once you know?
    Record it for future reference, in case the sights ever get knocked goofy, or your shooting skills go south in the future.

    Then, you have absolute living proof it is your shooting that went south, and not the sights or the gun.
    Sad, but true!! :D

    Oh!
    Don't do that!

    So, How much did you have to pay to get in??

    I still haven't got my first royalty check from the management yet! :(
