Do you know the condition of your Glock just by looking at it? Without picking it up and handling it? You should be able to tell. If the trigger is forward, consider the chamber loaded! Remove the magazine, and rack the slide, and visually inspect the chamber. Once it's determined to be clear, pull that trigger to the rear (dry fire), just like you would to break it down for cleaning. Leave the trigger back. All of my Glocks are stored with the trigger back and full magazine inserted in the safe, or until deployment for the day when I manually put a round in the chamber for carry. Leaving the trigger in it's rearward position does two things....1. relaxes the trigger spring (even the Glock owner's manual states this should be done for storage), and 2. let's you know visually that the pistol has an empty chamber. There is no way to have a chambered (live) round and the Glock trigger in the rearward position at the same time unless you are shooting it. Now you should be able to tell if your Glock is loaded or not just by looking at it from across the room or the minute you pick it up. Leaving the trigger back on an empty chamber Glock should become a habit...a good habit. It's simple and might very well extend your Glock's trigger spring life.
