I used to have a camera mounted on my paintball marker so that I could view the footage from the games. I suppose I could mount it on one of my 1911s but I would need to come up with a secure mount and a new holster for it. That would be fun for pistol matches. I am not sure if it would be any benefit for cops but, I know they are fun for other things. If this is a reasonably priced thing I would buy one just to play with on the range.
