Did they make the same sized pistol in a DA-SA version?
There I go referencing the SCSW. My 1076 has a straight Backstrap. With S&W I should know better than to say never.Yes they did offer the curved backstrap. I have XX26, XX76 guns with all three different grips, those being the palm swells, straight and curved. The curved backstrap fits my hand the best and seems to move my hand into a better position to depress the de-cocker lever.
Hope this helps.
