Dan,
I have given some thought to just what you mention, that a visible laser sight makes you an easily located target. I have not been able to decide what the likely outcomes are of using a visible laser sight, say for home defence or in case of attacks outside the home. In case of home defence, do the "aiming" or distracting (to intruder) benefits outweigh revealing your location? For personal attacks where shooting is at arms lenght, what, if any, advantage does the laser sight provide? How would you, or others, analyse this?
For me, the decision has been, as always before, to use a handgun that I can handle easily one-handed and point shoot accurately at short distances of personal attacks and even for potentially longer distances of home invasions. But, I have been using handguns off and on for decades, sometimes heavily.
For an even lesser practiced or skilled defensive handgun shooter, especially in a home defence situation, I am not so convienced about what is best. I can imagine aiming as best I can at someone breaking through a door -- there a laser sight might be great -- but, for other, closer encounters?
I suspect that this, like so many other aspects of defence, depends heavily on actual situation.
