I’ve been a firearms instructor for over 40 years. LE, Military and Civilian. I’m still active in the doing so.
For the last 5 years I’ve been running a Woman’s Only Firearms and Self Defense Class. I have ladies from 14 (with her mother) to 86 being my oldest student. But many elderlies.
First, I’m going to say I don’t like to recommend a firearm to anyone, not all of us are the same. My club and I provide several different types of guns for the students to try, to find out what fits them before they buy.
I will say, against my better judgement that two types do seem to pop up as the more popular. One being the Ruger LC series, the other the Smith & Wesson J Frame.
Some women have difficulty working the action on even the small semis. The small revolvers work better for them. Some don’t like the heavier trigger pull and the small semis work better.
You should try each to see what fits you.
Second don’t think you have to have a heavy caliber. Yeah they might be better, BUT, not if you cant shoot them. I’ve run across students who cant handle the 9mm, but are deadly with the 380. Therefore 380 would be a much better choice for them.
Also stay away from pistols with safeties. The less you have to worry about the better you are. Safety or not, no modern gun will go off if you keep your finger off the trigger.
In panic situations, people tend to forget the safety and try and shoot, then a pose, OOOPs, disengage the safety and shoot. I see this every night in class. And this in on a range practicing, how much more it stress going to be in a self defense situation.
But again, the best advise in choosing a self defense handgun is to try as many as possible to find one that fits you. You choose, not what others on the internet or even the instructor recommends. A good instructor will watch you shoot, then have you switch guns until you find one that fits YOU, and one that you can work without any effort or even thinking about. It should be the biggest caliber you can shoot COMFORTABLY and also small enough to conceal based on YOUR clothing choice.
Not all of us are the same, a perfect example, I carry a Smith J frame in my pocket. My wife couldn’t get a bullet in her jean pockets. Silly I know, but it proves a point, not all of us are the same.
