Then you will see how helpless you were
in the dark.
Disadvantaged...maybe. Not helpless. At SD ranges, I seldom use sights, or even look at the gun for that matter.
It takes Supper [sic] Man to see iron sights in
the dark.
If it's totally dark you can't see your target, either.
I have been shooting iron sights for over
50 years.
I've been shooting with and without sights for 35+.
Lazer sights can give you an advantage in
some situations. In others (bright light), they're useless. They are not gimmiks, but are another tool that might give one an advantage over an unexpected enounter.
One is not helpless without them, but may (or may not) be disadvantaged in any particular encounter.
I have two sets of CT lazergrips on snub-nosed revolvers, and I believe that they give
me an advantage
with these firearms. I feel no need for them on other firearms I shoot, and my primary carry gun does not wear them (G23).
I can look at an object, close my eyes, raise my G23 between my eyes and the object, and the sights will be lined up very well on the object when I open my eyes. This is one of the most natural pointing guns I've ever shot (for me).
I truly believe that a lazer sight can offer an advantage in some cases, but I also know that they are not
always needed on a carry gun.
