I designed that insert to get the officers to focus on a high center chest area. I got with my Doc buddy (SWAT Team Dr.) to hash over some ideas. The scoring rings were for shooting for badges. However, officers become programmed to shoot for the "bulleye's eye" / 10 box which is too low anatomically.I like your post first thing, thanks for your evaluation. Still want one. Wonder how far I would get with a go fund me acct for my own ACW? HA! Tell what that last target is, I like that alot, wan to give one a try.
