I would think for that price that they would go for a heavier caliber. Of course they probably have 'wimpy' in mind since there's no slide to take up some recoil.
$395.00 might make it go the way of the Gyrojet or the Tround.
On second thought, the WWII Liberator pistol is going for some high moola.

As far as safety is concerned "Hold my beer and watch this" Anything is possible.
