this is one of the reasons why when you look at some old ,say like 'stag' grips, you will often "see" ( as well as feel) one grip panel is fatter, thicker, than the other ...this is called a "palm swell" and the old grip makers would ask if you were right or left handed and that panel was made thicker, filling the palm and thus the fingers would be set back ,,which really didn't matter as a single action firearm, the trigger sets way to rear for single action firing.............lots of thought went into the design when you think about what your trigger finger is actually doing when firing a gun, in the different modes, single or double action, as well a when target shooting and you use ONLY the "tip" ( pad) of your trigger finger........... 8)
( let alone where you actually place the firearm in your grip......) :roll:
or the thickness, and width of the gun in questions' , trigger......... :wink:
