I’m 5’5 weigh around 110 and carry a Beretta Tomcat in .32 caliber. I use Glaser Safeties. It’s a small gun but packs a wallop .... my instructor says you don’t get into a shooting match and you don’t engage over ten feet ... you might consider that ... I’ve fired a Springfield model 1911A1 in .45 caliber and even with my small frame I can control it but the Beretta is the best for me ....
My wife carries her Tomcat .32 also. Has hollow points and thus, will do the job. I have always just told her to keep pulling the trigger till he hits the ground, then she can stop.
