There is nothing more important than Safety when handing firearms, and everyone should review/observe basic safety rules no matter how long they have been handling guns.
There are usually one of two reasons for gun accidents. The first is a lack knowledge about firearms- a person who handles guns without knowing gun safety rules, or how to operate a gun is exhibiting a dangerous lack of knowledge. The second cause would be carelessness- when someone who knows the safety rules but doesn't apply that knowledge.
In both cases accidents can easily happen. Please understand that when you practice responsible gun ownership accidents can still happen, but they are far less likely to happen.
You do yourself and every gun owner a big favor by taking the necessary steps to use/store guns in the proper manor. Here are some fundamental rules to gun safety, and when followed they insure a safe, fun, and productive life with firearms.
The first would be that you always want to have the gun pointed in a safe direction- this rule is very important because if the gun is always pointed in a safe direction -away from other people.
Always be aware of where the muzzle of the gun is pointing. The muzzle is the front end of the barrel where the bullet would come out.
Always keep your finger off the trigger until ready to shoot- When a person takes a gun in their hand it is natural to want to put your finger on the trigger. You have to learn to refrain from this action. Teach yourself to keep your finger out of the trigger guard completely until you are ready to fire the gun.
If at all possible keep the gun unloaded until you are ready to use it, and always treat every firearm as if it is loaded. I don't care how sure you are that it is not loaded treat it as if it is loaded. If you keep a gun in the house for self-defense always keep it in a safe place out of reach of children preferably under lock and key.
There are other safety rules, but these are the three basics of gun safety, and hopefully will get you thinking about gun safety. Remember the more you know about firearms and firearms safety the less likely you are to get hurt or hurt someone by accident.
