I recently purchased a Kimber 1911. My first 1911, by the way. I always like to make sure I clean every crack and crevice of any gun I own. With this gun, that means pulling back the hammer and swabbing in between. Eventually, I want the hammer forward again. Am I causing any damage, slide on or off, by pulling the trigger to bring the hammer forward? Some DAO's don't recommend dry firing, but then again, it's not necessary in cleaning.
