That’s so cool. I wonder how it works.
Its nothing new. The compact format is just a big improvement over large, shoulder mounted ones.
These are usually just wide band radio jammers that prevent the drone from receiving/sending data.
The news is that Ukraine is making these themselves now which will give them much more control and flexibility to respond to new requirements.
I kinda doubt that this pistol version is as strong or wide range as the big ones, but for personal defense this might be enough when a drone is coming after you directly.
Take for example this one used by the german bundeswehr as a size comparison.
Or this US military one which isnt even much larger than the Ukrainian one.
I sort of suspect it's a version of this:

It is. Just dump a whole lot of EM energy at it, and it (hopefully) stops responding. The antenna is in plastic for durability, and the giant cooling fin is because sending a whole lot of energy takes a whole lot of energy.
