When I was a cop, and later and armed Security Officer, I carried and used a PR24 to great effect. It was a pain to run with but there was nothing like getting out of the car and sliding the baton into it's ring - solved a lot of problems before they began
I found people had a similar "aversion" to the larger 4D+ Maglites 🤣
If it's marketed as a weapon, looks like a weapon or it designed for self defense it is illegal in Australia, if it could be used as a weapon you need a valid excuse to have it in your possession OR it's also deemed illegal.
I owned an Arlec 2AA (Mini Maglite knockoff) since the 80s which accompanying me on many "urban explorations" above and below ground, whilst I'm not a fan of the lanyard I do see it's inherent value 👍
