I was showing my new Glock 17 to a friend a couple of days ago, and the friend pointed out to me that I had an almost obsessive habit of checking to make sure the gun is not loaded. Before handing the gun to my friend, I removed the full magazine and them removed the round from the chamber. I then put the full magazine and the single round in my top desk drawer and locked the drawer. Then I put an empty magazine in the gun, and immediately removed the magazine and checked the chamber. Then I put the empty magazine in the gun, racked the slide back enough to show my friend the gun was unloaded, and then handed the gun to him, instructing him to keep his finger off the trigger. As soon as he handed the gun back to me, I removed the magazine, and checked the chamber to ensure that the gun was unloaded. Now, I knew that the gun was unloaded when I handed it to him, because I checked it. He was in my presence the entire time he held the gun, and I knew that he had not loaded it, because I kept my eye on the gun the whole time he had it (about 30 seconds). So why did I check it when he handed it back to me (his question)? My answer - to make sure the gun was not loaded. My friend is not a gun person, and has never thought about the process of handling a firearm, and how safety is paramount, so to him, my actions seemed like those of someone with Obsessive-Compulsive Disorder (his words). To be honest, it is almost obsessive. I know in my mind, that many times when I check my gun, that it is unloaded (or that it is supposed to be unloaded), but I check it anyway. I was not this way when I first started handling firearms. It is a developed behavior. Obsessive? Maybe, but I wouldn't want to be any other way.
