I carry one, but it's not really a gun for an older woman. As mentioned she may not have the hand strength to fire it accuratelly, and it must be carried in a good holster. The trigger must be covered and as mentioned it has a short grip, you need to try it first. I don't see it as a good choice. And pocket carry is out as it is just too bulky and you must not touch the trigger as it is even more sensitive than most other pistols, bumping or grabbing at it is a no no. Get her an lcp with a spare mag. Pick up an uncle mikes #2 holster and she will be good to go. At short distances a 380 will do the job as well as a 9mm. We carried ppk's and snub nose 38's , 20 yrs ago and never worried about power at 10 ft. Just make sure she learns where to place her shots, that's the whole thing, she will only have a few seconds from start to end of an engagement. A more powerful gun is only beneficial if she can keep it on target. Remember light guns have more recoil, and you will sacrafice weight for recoil in most situations.The lcp takes a certain amount of skill to shoot well, the main thing is that she practices a lot, and is able to get her weapon out and on target. If you go Glock, she must have a real iwb or owb holster. I just saw your mom is 6' tall, go for the glock, she has enough strenght to be fine with it, but try it first, the lcp may still be ok, the diameter of the round is basically the same in 38, 9mm, 380, and even 357, so hot loads like powerball or golden sabre, will make the same size hole just less powder, but at close range it will still put down an attacker fast if you hit them in the chest head, or a vital organ. It's the follow up shots that make the difference, a large perp may take 3 quick hits to go down in any of those calibers. The Glock has 10+1, the lcp 6+1, so you are at a definate advantage with the 9mm, in not only power, but amount of lead. But it's offset by the weight and ability to hide it, "carry", you need to decide which is more important. Having a 380, is better than not having a Glock, because it became too cumbersome to try to hide after a week or two.
