I could have sworn this was a 21" model, but I measured it myself, and it was only 20" long. Google searches doesnt even list 20" models, so I dont know.
ASP is the good stuff. It's what the police use. It's all black. The very tip, is a little silverish and has little marks on it. The ASP baton is a friction lock baton. So in order to collapse it, you smack it onto something hard. Like the ground.
Bought it new for $75 shipped a few years ago.
Will sell it for $30 shipped, Paypal only.
Check with your own state and/or local laws about the legalities of owning or possessing a baton. I am in no way responsible for it.
PM me for any questions.
