I do dry fire several times a week with my G 19. When reloading after I finish dry fire is it best to chamber the same round from the magazine or put the round in the chamber and then drop the slide. I heard putting the round in the chamber and dropping the slide is hard on the extractor. And by the same token constantly reloading the same round from the magazine is hard on the round. I keep two mags loaded with carry ammo and alternate them.
