Some of us have had unfortunate issues, with degenerative nerve damage that we have to use a mag loader. I use one for all of my pistols to get the last few rounds in.
Got bit by a dog in my left hand and all my ligaments now attach to base of left thumb. Max strength grip between 20-30 lbs.
Right hand is fine but I can’t reliably count on fiddly bits to make it So I use a universal sized magazine loader
But thats just part of life for me now, so I guess.
