The "fix" only works on models with a manual safety and only when the safety is engaged. If you release the safety, like many people tell you (as a matter of subjective opinion) that you should while conceal carrying, it won't do dick. Or even just release the safety because you're going to fire soon but not sure when -- same deal -- same flaw and it could go off without pulling the trigger. So the fix is as good as commercially useless, although better than nothing, the market is basically the guy who wants to be able to take it to the range and then always have it downrange while the safety is off.
