Rules of Gun Safety:
1. Never point a gun at anything you do not intend to kill/destroy.
2. Keep your finger off the trigger until ready to shoot.
3. Always assume a gun is loaded.
4. Learn how your gun operates, including the safety, magazine release, whether it is single or double action, etc.
5. Lock up and secure firearms when not in use.
6. Children should be taught age-appropriate gun safety, starting with do not touch and notify an adult if they see a gun (or even a gun-like object) and gradually progress to safe handling.
7. Do not handle guns when you are impaired.
Snap Caps - Do you know what snap caps are? They are actual size dummy rounds that you can use in your firearm for dry fire and other safe practice. They protect your gun from damage (you don't want to pull the trigger on an empty gun for fear of damaging the firing pin). In these days of expensive and hard to find ammuntion, snap caps are a great way to keep sharp on your draw, aim, and fire.
The old fashioned "as seen in the movies" trick of holding your thumb on the hammer while pulling the trigger and lowering the hammer on your gun is NOT SAFE. Most guns have a device in them to keep the firing pin from contacting the primer unless the trigger is pulled. It is possible to accidentally shoot your gun doing this. All it takes is a sensitive primer. If you must de-cock your gun, and it does not have a decocker, you should unload your gun before dropping the hammer.
