K frame Smith revolving carbine idea

[Ballistics in Scotland]

B in Scotland: if you put your finger near the front of the cylinder on a .357 or .44 Magnum the blast will strip the meat off your finger to the bone in an instant. Several pics of this on You Tube.

This is why you use a Weaver Style grip on a big revolver so there is no chance of your finger getting near that junction.

Indeed it would, but the Weaver stance is 100% successful, and keeps your hand further out of line than your face with a carbine.

This project will cost you an additional $200 for putting the shoulder stock on a pistol. The ATF considers a handgun as a gun to be fired with one hand.
The only time you can get away with not paying the $200 for the Tax Stamp is with gun like the Contender/ Encore that uses the same frame (receiver) for both a handgun and rifle. Also little semi-auto imported pistol that slips into a rifle stock with an existing rifle barrel in it.Attachment 169642

Wrong can not go rifle to handgun. Mount the over 16 inch barrel before the stock. Law is 16 inch barrel, 26 inch over all minimum

Looked it up on the ATF website. 26 U>S>C> 5845, 27 CFR 479.11. Ok to have a shoulder stock on a handgun as long as the barrel is over 16" and total overall length is 26" or more.
Don't know about going back the other way though except for the Contender/Encores and Galif pistol.
