When I got home last night I p/u my cb to see where my thumb is when I hold it and mine points down the rail,the reason I did this was because I was at the hangun range and Ive gotten so used to my left thumb being aaiming point andI wanted to see ifit was the same with cb and it was..so it a natual thing for me to point my thumb at the target and not have it up..One less thing for me to lose sleep over .
