I agree with B Wright. I am not covinced that 'gunfighter class' is a big help for me. I also carry a revolver and have a limit to shoots I can get on target.
Practice I do think is a big help, so I develop and practice drills I think would work for me. no one method is perfect so I say pactice what you think is practical for you, to be ready and comfortable with my gun is what pratice gives me.
