Getting a revolver would solve this issue pretty effectively
Huh?
How so?
Pulling a D/A trigger on a revolver can be every bit as difficult for someone with hand problems as racking a slide. Often more so.
Plus, with a revolver. you have to contend with the difficulty at the worst possible time - when racking the slide, you're just getting the gun ready to shoot.
When working the D/A trigger, you're actually going through the entire shooting process.
I happen to have RA flare ups from time to time which make it difficult to shoot.
Believe me, a D/A revolver (or D/A semi auto for that matter)is the absolute last thing I'd reach for.
Oops - missed giving the OP an answer...
Firestar M43.
They aren't made any more and you might have some trouble finding a good one used.
They also weren't the best made gun going either - but - they do have some real good points.
The M43 single stack is all steel and has a lot of heft to it.
It's roughly the size of a Walther PPK/s, but, has a wider back strap so it's much softer on the web of the hand during recoil.
The slide is also larger and has a more generous size to grip.
How they did the trigger/hammer spring, is beyond me. The hammer spring is extremely light and thumbing back the hammer requires no effort at all.
That, and the generous size of the slide and the heft of the pistol, make it very easy to rack the slide.
