It could simply be based on the current X frame hunter model. The shape of the grip area of the shoulder stock would have to properly configured to support efficient double action shooting.

I've asked a couple of custom smiths, but nobody seemed interested. I called S&W custom shop and the longest barrel they had in stock was 14 inches. Probably would be cheaper to register it as an SBR than have a custom 16 inch barrel made. But nobody ever did come up with any solid ideas on how to manage the gas blow by from the cylinder gap. Unmitigated, that would burn and lacerate my left forearm.

Here in PA, semi-autos are not allowed for hunting. So this would be the fastest shooting legal deer rifle to be had! I would venture to say, however, that one would probably have to hunt with active ear muffs, because I would imagine the blast would be significant and your head would actually be closer to it then if would if you were shooting a handgun at full extension. I hunt with electronic muffs now when I use handguns and this would be the same.

i would just as soon shoot my 45/70.....

PeteM:
Have a gunsmith attach a 2.5" muzzle brake to the 14" barrel and then you would be legal. ATF has rules on their website on what constitutes the proper way to attach a muzzle brake to be legal. A lot of the AR15/M4 rifles have barrels that are 14.5" and have the brake/flash hider attached to make them legal.
Sounds like an interesting idea, but where are you going to hold your "weak" hand to avoid flame cutting your hand/wrist, while still providing a steady hold?
If you do this, please keep us informed.

Photog,

A permanently affixed muzzle break to legal length....brilliant...why didn't I think of that?! Now if I could only figure out that burning gas issue.

Adudeuknow,

Double action shooting would be a bunch faster than your 45-70. I already have a guide gun. Don't get me wrong, I love it. But this gun would be one that nobody else would have but me!

How about a pump version. I've found a pump is a little faster than a lever-gun, and it would obviously not have the forearm-shredding cylinder-gap issues the revolver carbine would have. I, too, will stick with my Marlin 45-70. I sympathize with the desire for a one of a kind firearm, but sometimes no one else has one because they don't make sense mechanically/functionally. Good Luck.

Has anyone heard of a S&W revolving carbine in 357 cal?

I would think the blast/flash from the B/C gap would be pretty bad to your weak hand/arm (not to mention the proximity of the B/C gap to your face).

Well, here is "basically" what I just asked for:

Rossi 2010 What's New Catalog

I don't give a hoot about the 410 shotgun ability, so I'd much rather see a dedicated 454 Casull version built (should not be hard, since they already announced a 454 capable Judge revolver) that I know could handle higher pressures than the 45 Colt.

All the gun rags have is as a Taurus so I have no clue why they would list it in their economy Rossi brand?! I have never owned a Taurus or a Rossi, and the feedback I've heard first or second hand has been that you might get lucky or you might get a lemon - ie Quality runs hot & cold.

Anybody have any experience with Taurus firearms?
