TJ, the author AGREED with your objection to manipulating the slide with one's finger on the trigger. It seems that this "reset magazine" is supposed to address that by reseting the trigger so that all one has to do is just press the trigger 'shot' after'shot'--like dryfire with a double action revolver. I don't see what the problem is.
My issue is not with the author. TM is as down to earth as it gets. My issue is the realization last Saturday and now this article that Finger Violation tactics have been going on with Dry Fire RTR drills. Again, just my opinion, this is a terrible exercise with nothing to learn but a happenening waiting for an accident. Not sure who started or promoted this drill but if one follows this pied piper exercise then hopefully this new gadget will help. God forbid they just take some real training and learn how to shoot first.
