I don't know what it is about guns that have this dorky mid-century spy movie energy, but this just makes me want to get into a jumpsuit, lasciviously pose in some kind of bubble-shaped chair and keep spilling my entire bond villain masterplan to the agents i'm arresting inside of my expansive lair on the ocean floor while my trusted cadre of bdsm lesbian henchwomen point these surprisingly cool guns at them
I love this period in gun design where rails haven't completely taken over the industry, woods and metals are soooo last year, and plastic was still seen as a cool material.

I think it's meant to be more of a pistol-class weapon, so you'd probably have a more pistol-type grip. Not sure how ergonomic it would be though.
