Changed grip and finger placement, don't know if advisable

Made a topic before and asked if I was jerking. I've shot low left for as long as I remember. Compensated for it during my test.Today I changed my grip, and instead example 1 in this pic I tried example 2https://ift.tt/2qE1NP3 my first 60 shots of the visit 7yards https://ift.tt/2Fgy7BA big target are my first 15, the other targets are 15 rounds with the change of grip.I'm worried that doing this will only lead to more issues instead of not flinching/jerking . Or is this an ok adjustment.I'm also cross eye dominant. Right handed ,left eye Dom. via /r/CCW https://ift.tt/2qG0ZZS
