Just imagine when you go to the gun store to find a new handgun...and every single time they take one out, they explain in detail and repetition, "the gun is safe, here is my safety check, (mag released), making sure its safety checked, no ammo in the magazine, (rack slide rack slide, lock slide), gun is being safety checked, no ammo in the firearm, (rack slide rack slide, insert mag, lock slide), safety check compete, here you go." On each one. While I would have no problem with the extra safety precautions, I tend to go to the stores that treat me like I have some experience.
I prefer the stores that take the handgun out, lock the slide, visual check the top of the magazine and the chamber, and hand it to me. I release the magazine, and reconfirm empty, (usually inspect magazine quality and function at this time) reinsert magazine, and return the firearm into battery. I lock slide back when I hand them the firearm back.
