Course Outline

In addition to gun safes, locking devices can further help restrict access to a handgun. A locking device can prevent the gun from being fired accidentally. The following are common locking devices that can be used to secure your handgun.

Cable Lock

  • A cable lock prevents the action from closing on a live cartridge. To use a cable lock, open the action on your handgun. Run the cable through the openings, and the lock the cable.
  • Most guns are sold with a cable lock.

Trigger Lock

  • A trigger lock is designed to fit around the trigger guard of a handgun.
  • Common types can be opened by inserting a physical key or inputting a code.
  • Sometimes a padlock may be used as a substitute for a trigger lock. Slip the shackle through the trigger guard behind the trigger. This may prevent the trigger on some handguns from being squeezed far enough to fire the gun accidentally.

Barrel Lock

  • A barrel lock is designed to lock the gun from the inside. The insert is made specifically to occupy the same space where a cartridge or a shotshell would be.
  • It is typically locked with a key or other special tool.
