When I go to the range I "purposely" set up, one or two rounds in magazines and "force" a reload, which in turn gives me the repetition needed for "practice". I do the same thing in a class for students to teach and insure they have the procedure down safely. Then when I am confident, they have it or satisfied with my work, I go to reloading, when ever the pistol goes empty. One thing I stress is the difference in practice and training. Practice is the work on a specific skill set and should be designed to integrate that (one mag. with two rounds, one with three or dummy). When training, this is where work on bringing everything together, the only time I work "tricks" in is dummy rounds to "force" malfunction clearance. When training, I am a believer in doing reload whenever the pistol goes to empty, even at the end of a drill/session, you should have the "attitude sub-consciously" to reload the pistol. This is just my opinion. The last thing we want to do is ingrain training scars.
