The backing plate is not open behind the hinge for debris to get into as was demonstrated in the video. I also don't believe it to be an issue to remember to place your thumb on the backing plate while holstering. Some people have already been doing that practice to prevent the slide from moving rearward slightly.Exactly.. Only down side I can see is debris making it's way into a VERY vital part of the ignition system and you still have to remember to put your thumb on back of the slide when reholstering for it to function. Might be just as easy to make sure your holster is clear before putting the gun away. As Col. Cooper was fond of saying "your safety is between your ears".

I do agree though that proper deliberate holstering discipline is a must as well. I just don't see the harm in using this device to insure another level of security. Especially if one chooses to appendix carry.
