In general, I do not carry or use a baton or impact weapon but I could see the value of using it under limited conditions.
I and many other sworn LEOs, guards, corrections, SFs/MPs, etc know what an annoying pain it can be lug around a full size baton or PR-24.
I do like the ASP 21" and some compact style PR-24 units.
I'd carry an impact weapon in a 360 degree rotation type holder of kydex or man made material.
