I had the same problem, until a friend recommended this: the Handi-Racker - http://www.handi-racker.com/
It has allowed me to continue using and enjoying my semi-autos.
I do good just picking up a piece of paper as of today. Thumb surgery to repair a blown joint, torn ligaments and Trigger Lock, the hard cast put pressure on wrist nerves and damaged them AFTER 10 weeks of Physio my hand is still not usable for fine motor skills. Index finger is nearly as frozen as the thumb. I’ve 3 treatments left, and then Medicare/Tricare Life says your done for the year, even if the rehab is not working.
I’m doing 2 finger typing.....Can’t even turn a door knob or use eating utensils. Much less finer skills. Weight lift is 1 lb. That won’t even lift my Taurus Ultra Lite. Much less pull the trigger at this point.
