Assigning a specific death animation to a weapon

Voxel

Here's the simple version of my plan:

• I am currently working on a spy revolver model
• I want it to use the laser weapon death animation/texture/particles/etc

Is it possible?

If so how would I do it?

Skeindem

I think it's definitely possible.
I suggest you to decompile engineer weapons Short Circuit and Pomson 6000 and inspect their files.

While technically possible, I don't know how this kind of mods are done. Probably, you'll need to take a look at here in addition to Skeindem's suggestion:
