I am right eye dominant and naturally left handed. I shoot right handed, a when I did archery back some years ago I needed to shot right handed to lock down arrow shaft. For this reason I shot pistole (Glock 34) with the rigtht hand. considerd switching but I shot ok and the Glock 34 is setup better to use left handed. Here is the issue I tend to shot left and sometimes a bit high. I know that I flich as when the mag goes dry I tend to pull down, yet point of impact is really to the left not necessarily up or down. In fact I would say it is a sloppy pattern neither really high or low (more high then low if anyone is counting). what confuses me is that I should shoot low and left, but I shoot about even to the center or just all hits are to the left and mid or upper left of target. I was pulling the trigger with the tip of my finger. Based upon the idea that you keep doing the same thing you cannot expect different results. I moved pulling at the middle of the finger pad on the trigger finger. Results are still similar. I did move to the distal joint of the trigger finger, which I think improved the shoot placement. This was at the end of the day, so not entirely sure it was better (A lot of holes in target. I think the sights are lined up correctly as I do make some hits in first few rings center of target. I have been practicing Dry - Fire and I shoot at various house hold objects without much flinch. I think this is the case as I know the gun will not go off. I am now changing style to lower thumb to hold in power grip and using distal joint for trigger. When I used the thumbs parallel the the barrel I tended to ride the slide release, so every time I hit empty it would end up with the slide closed. I am not quick, so it took me awhile to figure this out, I was thinking bad mag. Reading article from Ayoob he said that Glocks were designed to use the center of the pad on index finger. Is using the distal joint ok. From what I read from the back strap just below where web of hand makes contact I measure 2-5/8" to front of trigger. If I measure my hand from web to the distall joint I get around 2-5/8". This is pushing with slight pressure to web of hand between index and thumb. I am right on the border line with the stock gun. Is it correct to measure as I have done to determine if gun fits you correctly. I do have adjustable sights, but I do not want to move the sights as this will not correct a trigger finger error. Other information is that I shoot both eyes open. I try to use the boxer stance along with slightly bent arms. I am 45 years old, but have had good vision over the years. With stock sights I do seem to have trouble keeping focus on the front site. My eyes play some tricks with trying to concentrate on front sight while obaining rear. I think the field goal glocks confuse the issue and cause my eyes to struggle back an forth. I am a new shooter, so maybe this will improve with time. Sorry for the rambling just trying to figure this out.
