What Handgun for arthritic hands?

[Ship A'Hoy]

Finally a firearms question I'm an expert on. I have rheumatoid arthritis and am rated at 50% disability because of it. It is in every joint of my body. I used to shoot double stacks but even a 9mm double stack hurt more than a single stack 45ACP. So my solution is to stay with single stack handguns. The one I shoot best is a SIG P239 in 40S&W.

The single stack semi is a good idea. I've found the old P225 single stack to be uncommonly easy on my hands.
