This has bothered me for a while. Living in a Northern state, shooting is a near impossibility in the winter months. Dry fire is the go to operation during this time. When I see instructional videos of some of the popular instructors/shooters, I pretty much see them all rack the slide to cock the hammer when making a point on shooting, grip, etc. Is simply cocking the hammer when dry firing wrong? That is the way I dry fire, and have not noticed any damage or degradation of parts that I can see. Would like to see what you all have to say on the subject.
