Setup and Installation
Follow these steps to properly install the Master Lock 90DSPT Gun Trigger Lock on your firearm:
- Ensure Firearm is Unloaded: Before handling any firearm, always verify that it is completely unloaded. Remove the magazine (if applicable) and clear the chamber.
- Separate Lock Halves: Insert one of the provided keys into the lock cylinder and turn it to unlock and separate the two halves of the trigger lock.
- Position Lock: Place one half of the trigger lock on one side of the firearm's trigger guard, ensuring the trigger is fully enclosed within the lock's opening. The protective rubber pads should be in contact with the firearm's finish.
