Salut and a happy new year!I have more than 25 years firearms, but still I have lots of concerns about the most efficient way to use them. I’m a big guy with the strong arm – the right one, right eye is the director one and I use both eyes open when shooting. Usually Glock 17 is my competition and self-defense gun (sometimes CZ 75 TS). I train regularly in dynamic scenarios with run, cover and atypical shooting position. Problems: 1. When shooting with the left hand, the time to hit popper placed at 10 yards is triple than when using my right hand. 2. After running, cover and speed shooting with the left hand, I noticed clearly my involuntary jerking the trigger, pulling the muzzle down, but without close my eyes. Therefore please tell me how you have solved theses:1.1. both eyes are open and bringing the pistol under the right eye. This is the fastest, but incomode.1.2. both eyes are open, pistol is under left eye and aiming slightly to the left than the desire point of hit. It seems to me awkward and hard to remember under stress.1.3. only aiming with the left eye and positioning the gun underneath it, the right eye is closed. This is the most accurate, but too slow and without peripheral field of view.1.4 ???2.1. No running to the cover for avoiding rushing time. This is not god if we plan to survive and not only whining a match. 2.2. For jerk compensate - aiming higher than the point I’d like to hit. Hard to remind at the moment of the truth.2.3 Reduce the speed of pressing the trigger – hard to do under intense stress. 2.4. ???..... it could be one answer for solving both problems: train with left hand as much and hard as with right hand. But even so, I can't rewrite the past 25 years when I allocate only 10-15% for left hand shooting techniques. So I need some hint and recommendation from you. Thanks!
