Four Reasons You Should Own a Firearm

Recent events have shown that our world is becoming increasingly dangerous. As a result, more law-abiding citizens are becoming responsible gun owners. Here are some of the reasons why.

Personal Safety

It’s hard to be a victim when you’re armed. Studies have shown that a firearm is the best way to protect your family and friends from the bad guys.

Home Protection

Home security systems are great, but what happens when they fail? Will your fancy alarm save your life? Will the police arrive in time?

Sport Shooting

Sport shooting is not only fun, it teaches patience, control, and discipline. Plus, it’s a great way to meet other gun enthusiasts.

Terrorism

The war on terror will likely be a long one. Responsible gun owners are our best defense against people who want to do us harm.
