Go to your local dealer/gunsmith. If you have no experience at all, I recommend a revolver. They’re easy to maintain.
I’d suggest the semi-auto Berreta Tomcat also. You might also want to consider one of the Smith & Wesson Ladysmiths in .38 special.
I have a standard service revolver, I just don't like it. Bulky and I think I shoot better than it lets me. But I intend to get some education shortly.
