In pistol shooting, all focus and concentration is on the front sight. The target is fuzzy and not moving, so you have no need to look at it. This is the most difficult thing, looking at the sights, especially under pressure. So a lot of my work in recent years has been forcing my right eye to look at the end of the gun.20yrs shooting Target rifle and still shooting, yes we are 'fiddlers', but after a while when you get it sorted you stop 'fiddling' and get more into the technigue side of it as it brings better results
My main problem was trying to stop my brain wanting to aim the gun at the clay, it's coming together now (6 months later) well it was until Covid19 raised it's ugly head
Now at the clays, I need to look at the target and keep my left eye dominant.
Total change....
And picking up on Will's wise words; I also believe that everything you can do to make it easier/more comfortable/natural makes things more likely to fall into place, rather than fall apart. Especially under pressure.
