I posted a thread several years ago about this same topic. After careful consideration, I decided not to purchase a gun at that time.
My situation has changed now - I’m still living in the same house in the ex-urbs of a major east coast city and I still have the same dog, but we now have three young children. This week, someone broke into a family member’s house just down the block from us. It was during the day and no one was home, but the family members work from home and it was just coincidence that the house was unoccupied. As near as we can tell, the alarm system went off immediately and scarred them off. The only losses are a broken window, a 12 pack of Corona (that was right next to some expensive wines and a case of Yuengling, wtf?), and a loss of sense of security. Mostly, this has driven home the point that events like this can and do happen even in our seemingly safe community. Seeing the broken glass scattered around my son’s toddler potty was a real gut shot. My wife is at home with the kids during the day and I can’t help but think “what if?”
As I mentioned in my prior thread, she’s mildly anti-gun but does have some shooting experience. This event has softened her stance somewhat and the topic is at least open for discussion.
Emotions are still high right now and I likely won’t make any decisions until things cool down, but I am revisiting the idea of purchasing a firearm for home defense. We already have a medium sized dog and an alarm, and I’ll be adding some motion activated exterior lights and a couple cameras. I was planning to add the cameras anyway so I know right away when we get deliveries at the house when my wife isn’t there.
I have very casual familiarity and decent marksmanship (under controlled conditions of course) with rifles and shotguns. I’ve only been pistol shooting once and did fairly well with 9mm, .38, .357, .45. Regarding a gun for home defense, is a pump action shotgun still the general recommendation?
