"The Big Gun" primary revolver

[radiant osprey]

You know the comrade's hammer from Cyberpunk 2077? That.

Single shot, heavy impact, mid to low range and an explosion where it hits.

For the fun of it, it could use a regular six shooter cilinder but fire the whole cilinder. And i mean, the whole thign, not only the bullets

Possible names include:
The Big Gun
The Big One
Pardner's Pick (a play on Comrade's hammer)
Three Hander (cause you need 3 hands to manage it)
The Mistake (self explanatory)
Revolter
