I agree with Elizabeth. There is a learning curve that you MUST commit to, to be safe owning/using a gun responsibly. That learning curve includes regular sessions at the range (1-2 hrs a week) and 100-300 rounds of ammunition per session. So you are looking at a time and $$$ commitment at a time when demand has pushed costs high.
Your decision, given your risk assessment of the potential danger to you and yours. Don’t get a gun unless you’re willing to commit to the training. Otherwise, you’ve increased the risk of problems, not decreased them.
Good luck...be safe!
