Why in the world would you store your pistol with the chamber locked open and safety on?! I carry my Glock 23 on my person with one in the chamber. That’s the only way to carry. If I need to store it in my vehicle because I’m entering a prohibited area I leave it in Condition 1 as I store it.
1. If I am pulled over and have to present it, as I am grabbing it I can release the magazine and present it unloaded.
2. My wife has never been good at chambering the first round. This way it is easy for her to chamber the first round.
