I test fired a Kahr a while back, and even with small hands I engaged the trigger with my distal joint.
I found that shooting it like that my index finger stopped the pull against my thumb just a hair before the trigger broke.
I've seen suggestions such as a straight thumb hold or using the middle of the pad of the index finger, but was wondering if a mechanical solution was possible.
Could someone build up the trigger face maybe 1/8"?
I know, training, ammo, etc, I'm just looking for options.
