....I don't have overly large hands (tho do take a size "L" glove), and find that I need bigger stocks on my J frames to keep my trigger finger in DA fire, from contacting my thumb while firing. When it does, it invariably knocks my shots off to the side of the group...sometimes by a considerable amount, especially at speed. I guess what I'm saying is that for DA fire, the J-frame is about the practical limit on how small you can go without interfering with firing function/accuracy. What say you? Rodthe world needs a quality DA smaller than a J frame
