Not sure if this is the right place to post this...
I have 3 K-frames, a 10-5, 14-3 and 19-4 and the same shooting discomfort with them: in double action, the gun whacks the base of my thumb, even with medium loads (4.0 gr. 231 over 158gr in the .38 Spec.) But in single action, presumably due to using the tip of my finger on the trigger rather than the crease of my finger, and thus a slight shift in my grip, I don't have this problem.
The grips on the 14 and 19 are Targets. The 10-5 came with Magnas but I have put Pachmayr Grippers (? finger grips) on it. All three share the same open back design. But I have "medium" hands and closed-back grips will likely be too big, at least based on closed back Pachmayrs I tried on my 625-8.
Aside from shooting grips, is there a tape or "patch" I could put on the top of the frame where the base of my thumb meets the frame? I like the wood grips aside from this problem.
I also have a Ruger GP100 4.2" that has rubber Altamont insert grips on and the last time I shot it I don't recall the same problem (with moderate "38-44" loads) but those grips are closed back and wider at the top, which presumably spreads the recoil over a slightly wider area.
