DO NOT PRACTICE THIS WAY
2 things you should practice
1 sight picture with both eyes open
2 muscle memory
If you practice these with the firearm you are carrying or plan to carry, it will be like not using sights, because you have the muscle memory. you will know how the gun feels if you practice. you should at least practice once a week ether out on a range or dry firing in side. look at your 2 test results. it proves you should not do what your saying, you hand 3 stragglers witch are 3 bullets you have no clue where there going, actually all of your bullets you don't know where there going because you don't know where your aiming. if the end of you barrel moves 1/8 of an inch at 20 feet you could miss your target by 4 inches. if you are in a crowded area that could be innocent people shoot and you don't want that your bedder off just learning the muscle memory with your sight. it takes the same effort as what your trying to tell people to do and if people do what your saying that's blood on your hands.
STOP practicing this way and start the right way
