Husband: What a beautiful day. Let’s go for a hike in the National Park.
Wife: That’s not a good idea. There are Grizzly bears out there and they have cubs this time of year.
Husband: Not to worry my dear; I have my trusty 9MM in my pocket.
I wouldn’t feel good about shooting a bear with a 9mm.
9mm against a Grizzly? Good way to get et.
Upgrade to a 10mm, if you don’t want to be on the menu.
