I was trained in the use of the PR-24 by Arbrey Futrell. For those that don't know Arbrey Futrell, he is the LEO instructor from Louisiana that came up with the most powerful strike with the PR-24. It is called the Arbrey Futrell Power Strike. It is the only strike with a PR-24 baton that is capable of breaking the Femur.
I was also trained in the use of the ASP. I carried an ASP on my belt and a PR-24 in my car for about two years and then switched to the Monadnock expandable side handle baton.
I remember arriving on a call as backup not long after I started carrying the Monadnock side handle . Two younger Officers were out with a guy that was about 6' 250 lbs. When I got out of my unit I could see the guy was pissed and chipping his teeth (talking trash) to the two officers. Once I got out the guy stopped talking and put his hands on the hood of one of the officer's vehicle and became very calm. They checked him for weapons, to which he had none, and ended up writing him a summons, I don't recoil the charge. But once they were done one of the younger Officers asked why he went from being aggressive to being compliant.
The guy said, Y'all carry them little sticks, then pointed at me, But he got out that car with gloves on and that stick with that handle. I knew he meant business, and it's harder for y'all to carry that stick with the handle so I knew that he knew how to use it. And I didn't want him to hit me.
I only had to use my Monadnock expandable side handle baton once. All I will say about that is the guy wasn't happy and I had to do a lot of paperwork.
