with the name of a gun, ASP

https://en.wikipedia.org/wiki/ASP%2C_Inc.

It's also the name of tactical batons; the sort that extend when you swing them, but are otherwise about the size of a flashlight.

ASP manufactures telescoping batons. An assessment by law enforcement officers found them preferred to the usual straight baton for their portability, convenience, effectiveness, usability, and psychological impact.

Since the early 1990s, ASP batons have been adopted by law enforcement agencies in the United States, United Kingdom, Canada, New Zealand and Australia. Expandable batons in general are sometimes referred to as "Asps".
