    Smith & Wesson 459 semi-auto, pretty good shape but the sight lifts up, is that normal?
    A friend asked me to take a look at his pistol for him because it wasn't shooting straight. I started adjusting the rear sight when I noticed that it was wiggling a bit when I would put the screwdriver in the adjustment screws. Well after 10 seconds of looking at it, I realized I could lift the whole sight right up using my finger. Not real far, maybe 1/3" or so, but I could definitely lift it up from the top of the frame. It seems solid like there is a spring that is trying to hold it down somewhat, and it doesn't pry waaaaaaay up because there is something solid anchoring it, but will flip up with finger pressure.
    So me not knowing ANYthing about 459s and darn little about sights in general, I thought I would ask the revered body that is The High Road.
    Can anyone here help me out with this? Is this normal, or devastating, or somewhere in between? All help is appreciated, thanks.

    The sight aperture has to have some movement in order to adjust. Now if you're referring to the entire sight assembly (sight blade & sight base) are moving then yeah you've got a problem. However having dealt with many a shooter that can't admit they can't shoot that particular gun; scream that it must be an issue with the gun. So in other words make sure the shooter isn't the problem.
