Quel système de visée avec une lampe tactique sur un glock?

The other trend that I have noted in regards to the use of sights is the
actual configuration of the sight itself. I have noted two distinct
categories of individuals who remember using their sights; they are those
that used long guns and those that used a revolver. The reason for the long
gun use of sights seems to be directly related to responding as one is
trained. All that I spoke with advised that when they saw the threat facing
them, they brought the gun up until their cheek connected with the stock and
the fired. None of the people I spoke with advised that they had ever been
taught to fire their rifle or shotgun from the hip. When asked why they
remember their sights, a common response was, "Because they were shoved up
in front of my face."

Revolver shooters continuously told me things like, "I remember that big red
(or orange, or green) front sight coming right up in front of my eyes and
laying right on his chest." For those of us who broke into defensive
shooting using revolvers, we can remember how well that red front insert
contrasted with the wide black rear sight on our Smith & Wesson Model 66 or
Ruger Security-Six. Those of us who did not have such an insert would
usually paint our front sight with some high visibility color. Think about
what is now available on semi-automatic pistols. We now have to line up
three dots or we have to place a dot on top of a bar, all of which I believe
is too complicated for our eyes to do quickly. The revolvers simple, but
contrasting, sight system was easy for the eyes to use under stress.

Dr. Godnig reports on this phenomenon, "Contrast of a target is a critical
variable directly related to ease of visibility. Contrast corresponds to the
ability to discriminate a dark visual image from a lighter visual image
within a total visual surrounding. In general terms, contrast is the
relationship between the lighting intensity of two adjacent areas. A dark
image, approaching black (having no reflected light) is most easily seen
next to a white (reflecting all light) background. Shades of gray that
mostly resemble each other in light intensity and reflection are most
difficult to visually discriminate and separate because the contrast values
are most similar." Dr. Godnig also states, "Size of an object is related to
visibility because relatively larger image sizes have the potential to
stimulate more retinal cells inside the eye resulting in higher numbers of
cones and rods sending information via the optic nerve to the brain for
visual information processing." Objects that are large and of contrasting
color are easier to see under stress, which makes the current generation of
semi-auto sights on the wrong end of the sight plane. I, for one, have
highlighted the front sight of all my pistols with bright orange emergency
warning tape. It offers a contrast that is large and bold and I feel is the
reason that I can recall my sights during high stress events.
