Having no formal training in hand gun shooting (other than safety), I greatly appreciate any and all info that I can get to increase my accuracy & speed.
Is everything I read the be all and end all? No, I try it and if it works then I stick with it. If not, I go back to where I was before and keep moving forward.
Those that already have training, or a system that works for them, then there is no reason to change it. I think is good that some of you try it, but there is no reason to say that it is incorrect, it just does not work for you.
