Saboteur 67 Ultra Wave Equalizer

If you're not familiar with Dr. Grordbort, you need to acquaint yourself. It's a rabbit hole of much steampunk goodness "where science meets violence". This pistol by Grantmasters was inspired by the Saboteur 66, one of a great many whimsical and wonderful steampunk weapons featured. It's small, much smaller than you would first think, but t's powerful.
