To answer the OPs question, yes I have one. Yes, it'll work. They're tough lights and can take (or give) a justified beating.
I found that ASP batons were over-rated and ineffective. They also don't always "deploy" as you would like them to. An old style nightstick had nothing to "deploy" and was ready to rock, much like a solid Maglite.
I was never a beat cop but did private security in very rough areas many years back, before going into private sector investigations. We had to carry them. They sucked compared to an old style nightstick or blackjack, etc. That's why I also carried a Maglite. That was what I'd be reaching for if I had a fight, not the ASP baton. Most guys had their fancy little "tactical flashlights" that were small. I ran the Maglite knowing, that's my main hand to hand weapon.
You can find videos of cops beating people with them and them not having much effect on stopping the bad guy's behavior. I don't think punks of today are tougher, more so the tools aren't as effective. I think honestly, the ASP came about to limit the bone breaking power of a real nightstick. More so a political move in my opinion.
I always love talking to guys who were cops back in "the good old days" and they get a little glossy eyed recalling things like slaps, blackjacks, and nightsticks.
