Have you recently purchased a firearm, but are a little uncomfortable with handling your new form of protection?
Take a safety course to familiarize yourself with how to handle your weapon, how to clean your weapon and how to properly fire your weapon.
Being scared and/or uncomfortable with your weaponry can be dangerous to you and those around you. Once you are educated and are taught how to fire and handle your firearms, you naturally will become comfortable.
You can think of it as learning to drive a car. At first, it is an unknown and can be scary, but once you are educated and have practice, the fear goes away.
