Gun Locks and Chamber Flags
So far, we have talked a lot about safe firearms handling. Preventative tools such as gun locks and chamber flags are equally important.
Gun locks allow you to easily transport or move a firearm around your home without any possibility of the firearm getting loaded.

Also, helpful on the range or in the safe are brightly colored chamber flags. Chamber flags allow for quick identification on the loaded or unloaded status of a firearm.
