Full N Fll,
it is impossible to ignore the barrel totally that's B/C we have the gun in our peripheral vision when we shoot!
Keeping the visual focus on the target and the gun in the peripheral vision will help us to connect to the target and establish the sight picture.
B/C we can't eliminate the gun from our peripheral vision the eye cross dominance
is a big problem to line up the gun correctly and establish the gun target relationship.
First,trying to shoot with both eyes, you need to have the gun beneath the Master eye, second, you have to ignore the ghost barrel by working with the " right" barrel.
Indeed if you use a dot or tape, that's not shooting with two eyes even both eyes are open.The dot tape will cut the two eyed shooting to one eyed shooting!
The big difference between the dot, tape, and the XDS is that the XDS allows
both eyes to see the target( two eyed shooting),therefore the XDS is not a total blocker but a semi blocker. Will limit the master eye to see the barrel but in same time will allow it to see the target!
The XDS will fix not only the eye cross dominant handicap, but also the cross firing phenomenon.
The concept on which the XDS was created is on the website
