Remember the OP has arthritis...Yes, I'm quite aware of that. That's why I didn't ONLY mention rifle shooting. The majority of my response was referencing pistol shooting.
The guy I mentioned with the end of his index finger missing was a Fed agent and had no issues qualifying with a SIG P229 in .357SIG. Plenty of recoil there, much more than a S&W 908. He easily qualified on both the old Tactical Pistol Course and the newer Practical Pistol Course.
