...so, where can I find literature of what you mentioned in another thread about the grouping, etc. ?  I seem to be hitting within the target area, but grouping it low and to the left (50 feet).  I'm accustomed to plainking with a .22 caliber for target practice, with it, my grouping is tight and centered but not with this .40 S&W. Low and to the left.
(Out of fairness, this .40 frame is quite abit heavier than  the .22 as well)
Suggestions, websites, books?
