I suppose having a defense weapon is better than not. Reviews for Hi Point are all over the place. Some have no issues, some have many. The biggest concern I would have would be with the size of the slide. Some reviewers claim that the slide impacts their thumb, and tries to take skin with it. That would be very painful, but I'm sure that varies hand to hand. I once had a 45 that had a hammer that would sting my hand. Not a good feature!
Others don't like the feel of the safety and find it hard to disengage. Again, a factor of hand/finger size and strength.
Basically, you want something reliable that is comfortable enough to use when you practice at the range. If your hand is sore after a few magazines, it's probably not a good deal.
I have never shot a HiPoint, but I have shot a fairly wide variety of hand guns. One of my favorites is the M&P compact 9. It just fits my hand great, is accurate (especially for a short barrel), has moderate kick and has never failed to properly cycle. Plus it is cheap and fun to shoot, which means you will practice with it more. It is also about 3 times the price of the HiPoint. Still a good deal.
The best thing to do would be to go to a gun range and fire a few different models to get a feel for what you like or don't like. You may even want to consider a shotgun, as there is less requirement for accuracy and less chance of a stray bullet penetrating walls and continuing (although that can be mitigated somewhat).
If you are unfamiliar with handgun use and safety, I definitely recommend a class. There are online classes for about 20 bucks to hands on courses that run 150. Good luck!
