This was brought up to us during training. The solution was instead of handing it back to your training partner to go again or reverse roles they instructed us to toss the gun (blue plastic) on the mat beside them. I thought that was almost as bad as handing them the gun.I remember a story from years ago of a LEO who would train disarming a perp. During these drills he would hand the gun back to his training partner. Fast forward to a situation where he actually used his training and disarmed a perp I real life situation, He then automatically handed the gun back to said perp! From my recollection LEO was able to gain control of the gun again.
