Eye Dominance, Sight Alignment / Sight Picture and Sights.
Recently while practicing off (weak) hand drills with my new Colt, I had a disturbing revelation, I was shooting better with my left hand, not just because I was using my left hand, but because I was using my left eye.:confused:
This led me to retry shooting with both eyes open, I have been trying to transition to shooting to both eyes open for the last 6 months or so, and I was having no luck, I couldn't get clear focus on the front sight.
When I went back to shooting with both eyes open I changed the position of my head moving my chin more to my right, placing my left eye more in line with the sights, and presto I had crystal clear sight picture.
This confused me at first, because I've been right eye dominant for as long as I've been shooting. When I performed an eye dominance test I was shocked to see that I was now left eye dominant.
So now I'm in a rough spot, I'm right handed, left eye dominant, and I've been shooting with my right eye for the last 22 years.
In trying to overcome this new affliction I've discovered the following things to be true:
1: After "X" amount of years using my right eye I can't keep my left eye only open for very long.
2: Dry firing exercises utilizing snap caps works wonders.
3: In order to correct my weaker yet dominant eye, I have to shoot with just my left for a while.
I have also reevaluated my needs in sights for my pistols.
I have opted to give the XS 24/7 Big Dots a try going on the theory that the larger front sight will be easier to focus on.
While using my left eye only, or prolonged two eye usage I was "loosing" the front sight in the rear, my sight picture startes looking like a fuzzy black box, instead of a clear front sight centered in a fuzzy rear sight.
I am also going to eneavor to use my left hand more and try and build my weak hand pistol skills more than I have in the past.
I ordered my Big Dots for the Sig tonight, unfortuantely I am out of town for the week and won't be able to practice anything while I'm gone (had to drive through NJ and NYC and I didn't even want to risk a traffic stop with firearms in either state) but as soon as I get back Lima should have the sights installed, she opted for the standard XS 24/5 dot sights for her Kimber CDP to replace the fading factory 3-dot night sights.
As soon as I get a chance to utilyze the Big-dots I will do a complete range report with the Sig w/ XS sights compared to my factory 3 dot sights on my Colt and the Novaks on my Springfield.
In the mean time I will be researching eye dominance further and trying to find other ways to "strenghen" my left eye use.
