Shotgun pistol

There's a big difference between a revolver that can use shells versus a short pump shot gun. For one thing, how many hands is each designed to use for operation?

Handguns are considered designed to be operated with one hand.
Pumps are considered designed to be operated with two hands.

One is fine but the other requires lots of paperwork.



(And no, it does not need to make sense)

 

You can get a Serbu Super Shorty if you don't mind waiting on a tax stamp.

Smooth bore pistols are AOW's

 

If it was made at the manufacturer with out a stock, and never had a stock on it, you go as short as 26.1 over all length without it becoming and NFA item.

The Judge is a .45 Long Colt revolver with a rifled bore meaning it is not a shotgun. It is incidental that the chambers are slightly elongated and .410 shotgun shells can be chambered.

Smoothbore and shorter than 26" overall is an NFA item classified as an AOW (Any Other Weapon) unless it happens to have a shoulder stock...in which case it would be defined as a short-barrelled shotgun if the barrel is shorter than 18".

Editing to add:
I haven't yet found a break-action shotgun that comes from the factory with only a grip and not a full shoulder stock. The significance is minor as modifying a stock to a grip and cutting the barrels shorter would require the same NFA process as taking a pistol-grip break-action shotgun and cutting the barrels.

If you wish to go through the NFA process ($200, prints, waiting), then you can basically have any length of shotgun you are comfortable using.

 

If you want what is functionally a sawed off shotgun and you do not intend to fire any regular cartridges through it --only shotshells buckshot or slugs--- you can have this IF YOU BUY a certain type of firearm that looks like a cut down shotgun but is actually a non-shotgun firearm because it was never intended to be fired from the shoulder and it comes with a pistol grip only . Such a fire arm would never ever have had a shoulder stock on it from the day it was manufactured .

If the overall length of this weapon is more than 26 inches, that takes it out of the A0W category.
Since it was never intended to be fired from the shoulder, it is not a "shotgun" either.
Since it never was a rifle or shotgun, shortening the barrel ( or purchasing it with a shorter than 18 inch factory barrel) is OK .
The trick is getting a gun that has a short enough barrel and still exceeds 26 inches overall length .
I've seen this done with break open shotguns by elongating the pistol grip extending it backward a few more inches from the end of the receiver rather than putting it directly below the back of the receiver .

 

The operative phrase when discussing firearm "laws" and "regulations." The MA Attorney General recently reinforced that mantra with her reinterpretation of MA's assault weapons laws.

 

+1 I'm going to build an 870 like this soon, they can be a little hard to find. Most end up doing these conversions with Mossberg's.

Thompson Contender, with .410 barrel

 

I'd like to see somebody invent a 3 or 4-barreled 20 gauge shotgun/pistol (legally an A.O.W.)
Break-open action.
It should have 6" barrels and a normal sized pistol grip.
Give it a forward handgrip option, too.
Maybe let it come with two fore-ends. One plain, for easy carry. One tactical, with a second pistol grip up front and a built-in laser/light unit.

 

Very...very close to what you requested:

always have been a big fan of the Ithaca Auto & Burglar, but unfortunately it was incorrectly classified as an AOW a long, long time ago.

 

(I see what you did there)
