No stories since owning a firearm, but I will gladly share the one that led to me buying one.
First and most important fact: At the time of this story I lived, worked, went to school, and spent my free time in Flint, MI.
While at our rental house just a few months after our wedding, my wife and I were in bed just about to fall asleep at 3 AM or so. Our doorbell rang, and being the naive 22 year old I was at the time, I got up, went to the door, and stuck my head right up to the glass to see who it was.
To my surprise, it was 2 large guys strait out of the ghetto... decked out in colors (Red... not sure what gang that goes with in this area) and an Impala in my driveway.
Mistake #2: I opened the door. I should mention they were outside of the storm door of my screened in porch, a good 10 ft. from the door. After a very short conversation, I told them to <removed> and shut and dead bolted the door to the house. That's when the scariness started.... pounding/kicking the door. Me with my 290 lb frame pushing against it.... Wife on the phone with 911. They showed up, 1 of them took off in the car but the other was taken in.
The next afternoon, I called my best friend... an avid gun activist and resident of Flint. He took me shooting at a local range. That led to me purchasing my first firearm: a mossy 500, my first pistol this last year, and taking my CPL class this coming June. The day we found out that we had a little one on the way (about 8 months from the incident) we found a new place. The old house has since been burned to the ground.
I am very thankful that things didn't end poorly for us, I would be lost without my family.
For anyone who is unfamiliar with Flint, I would encourage you to spend some quality time with google on the issue.
