A couple of ideas may be helpful in extending your time with auto pistols:
With a hammer fired SA or DA/SA pistols, you can cock the hammer. With the hammer cocked, the force needed to cycle the slide is greatly reduced.
The other day I installed a red dot sight on my Glock 34. When I went to cycle the slide, it was suddenly real easy. You can run the side of the first index finger nuckle against the sight and cycle the slide without needing to grasp it.
The one subject we all become experts in, like it or not, is coping with the changes the passage of time forces on us. Stay happy.
