I do understand that argument, and carried my striker fired pistol, chambered, for a very long while. But it tends to wear on you. Plus I carry Ruger, not Glock. Glock has a lot of patents that I don't think Ruger has, and I am not sure they are quite as safe (but they probably are.)
The peace of mind that I am afforded by knowing that there is no direct relationship between that bullet and my body, is important to me.
