How strong is your mom? The reason I ask is I recently went shooting with a female friend of mine (25 years old). She is very petite and had difficulty manipulating the slide on my semi-autos. While she was able to do it, it was a real struggle for her. A wheel gun is probably the best option if your mom's hand strength isn't up to the task. I would recommend that you have the trigger worked on since most revolvers have long heavy trigger pulls. Most people recommend against cocking a double action revolver in a self defense situation since the trigger is so light in single action. A small 5 shot revolver is probably ideal, but make sure it has nice grips on it. My friend had a .38 special revolver that kicked quite a bit and hurt her hand when she shot it. To be honest it hurt my hand too. While the gun had rubber grips, it didn't cover the back of the grip and the frame of the gun recoiled directly into my hand.
The other option is to go with a little Beretta with a tip up barrel. I bought my wife a Beretta Tomcat in .32 since she isn't able to rack the slide on my semi-autos. Semi-autos are much more efficient for concealed carry since they can be much slimmer than revolvers (no cylinder). For the same sized gun, the semi-auto will have a longer barrel which gives higher velocities and better accuracy. For the same size, semi-autos typically hold more rounds and reloads are much easier to carry since they are flatter. While revolvers can be loaded very quickly, most people can reload a semi-auto much faster.
If hand strength isn't an issue, a good option might be the
Kahr P9. I personally carry a PM9, but the small size only allows me to get 2 fingers on the grip. That makes it harder for novices to shoot well. Another good option may be a sub-compact Glock such as the 26 if she hands are big enough to hold the fat grip.
Best of luck to you and your mom. A few things to possibly consider doing immediately:
- Already mentioned above but... Change locks.
- Buy her some pepper spray such as Fox Labs.
- Get a monitored alarm system.
- Install a CCTV system in her home.
- install arrive way alert system such as

- Create a "safe room" with a reinforced door, strong locks, and good hinges.
I am not crazy about getting a aggressive dog since she may not be able to handle it. Besides, dogs can always be poisoned or shot.
Hope this helps!
