I wouldn't even consider anything but a revolver with a decent trigger. Most in this situation don't practice or care about the gun except for having it. Easy to check for loads and simple. The trigger generally sucks so some help there would be needed. Racking the slide is always an issue, simple mag changes which generally would never be needed are a challenge. My wife who is very fit for her 68 years can't rack the EZ 9. I was shocked, figured it was the ticket other than being too large for her to carry. She carries a S&W 638. I've tried other options but she so far wants to stick with the Smith. Again the trigger isn't great but with a little adrenaline I guess it works.
At 86 I pray grandma will never need a gun for defense. If she just loves guns like me and then more power to her.
