Breaking in and zeroing a Shadow Systems MR920P

I only had one malfunction -- a failure to reset the trigger (at about the 5:25 mark).
Of course I forgot my targets, so I had to improvise and re-purpose old targets left behind by other shooters to zero my green dot.
I'm going to run it through a couple of IDPA matches before I decide if it becomes a part of my EDC gear.
