I was shooting a type of IDPA, using my M&P22 pistol and when doing a fast reload from slidelock, the top round would stovepipe. I found it was because I was ramming it in too hard and the top round would pop partially up from inertia and then not feed correctly. The mags are all adjusted perfectly and I wouldn't want to tighten the feed lips any more than they are, so I tried the soft reload and no more problem. Only adds a small fraction of a second to my time and saves having to clear a malfunction.
