A little .22 did the job. Don’t feel under-gunned if you can’t handle anything else. It’s better than a club or a kitchen knife. Actually, I’d have all three in the house ready for use. The nice thing about the .22 is that if it doesn’t stop them you’ve made it known you are willing to resist. That is much better than submission. Just because it didn’t stop them doesn’t mean the fight is over. Sometimes they run and sometimes the fight has just begun.
