I am just over 50 and have been learning this gun thing. Done some IDPA and STEEL MATCHES at my local club as well as taken a pannone class as well as a frank proctor class. I have learned a lot through this instruction. Over the winter I decided to get better by dry fire and this is where it starts to hurt. First I gave my strong hand trigger finger. After both PT and a shot the trigger finger went away. My therapist suggested using more tension with my support hand to reduce the crush grip and now I have tennis elbow.
It will get better however here is what i would like to know.
How important is it to squeeze the pistol.
Which grips tend to reduce these tendonitis type issues.
BTW also a crossfitter and decent chest and arm strength. About 80+ lb grip strength.
