I’ve seen them bent from the impact with a person and cause very little if any effect (I’ve never used one on a person as an impact option. I’ve used them to pry arms out and to apply pressure point pain compliance techniques.) They work well for poking a drunk awake or wrapping some tape around the end to fish your evidence out of the bin slot when you forgot to put the bar code on, er hypothetically I’ve heard. Guys that used them when they were still authorized before I started had good things to say about the slappers and how effective they were.
