I'm an NRA Pistol instructor and mostly work with veterans groups. I teach the NRA Basic Pistol course which meets the state requirements for a CCW here. Most of my students are vietnam era vets who are in their 60s now, I've also had several Korean and WW II folks who are in their 80s and 90s. So, as you might guess, arthritis, recoil sensitivity and hand strength are often issues.
I usually bring my wife's SP101 and a few other pistols for students to try out at the range. Older folks tend to have a hard time with the SP 101's sights. But the revolver with mild .38 loads is easy on the hands. I've had several students go on to purchase the SP 101 for CCW / HD after the class.
One lady bought an SP 101 but found it to be too heavy for daily carry, so she also went on to buy a S&W Air weight .38. Last I talked to her, I offered to help her sell the Ruger; Her response was awesome, "Oh no. I will keep that one to shoot and just carry the lighter one."
I suggested she take the Smith out to make sure it works at least, but in retrospect; that is a pretty clever approach. A Ruger SP 101 in .357 Mag teamed up with a light weight J frame .38 covers a pretty broad spectrum of carry situations. From trail gun to light weight sumer carry piece.
