I'm instructor of ASP telescopic baton, I use your method but in Italy the tactical baton are illegal for law enforcement. Just a fixed one flexible enough around 60 cm, 25"
They use the ASP here as well.
Also a lot of departments are banning metal flashlights, to easy to use them around the head and neck area. Plastic flashlights it is thought would break before they could to any life threatening damage.
