My first handgun was a used ruger p95 9mm. For $300 I never had an issue with it and fairly accurate and budget friendly. I bought it after handling/shooting several until I found something that fit my budget, shot well, felt good in my hands. I suggest doing the same and finding a handgun that fits you. Since then of course Ive upgraded to higher end pistols.
Good luck and take your time searching.
