One of my pet nightmares is being chased by "goblins" at night, breaking into a gunstore, discovering that they have every calibre of ammo going bar the one for the pistol in my hand and further discovering that the law abiding owner has taken steps to ensure that the weapons on display are unusable. As a firearm for a worse nightmare/emergency use, that revolver has a lot to recommend it.
I note that it's construction is substantially stronger than the norm.
