How feasible would it be to make a cartridge conversion? I know that there were a few cartridge LeMats made, but they were complicated and not too successful. I think the main problem was in designing a breechloading, cartridge central (shotgun) barrel. Why not leave that as muzzleloading percussion, while having a cartridge cylinder? The gun could be sold in its 100% percussion form (completely free from regulation being an "antique"). The cartridge cylinder could be available separately as an accessory (also not subject to regulation).

The same concept could apply to the pistol version.
The center shotgun barrel is not feasible but the revolver portion has been done before
 
None of the others give the nine shot plus one shotgun firepower , and pietta made these but only a hand full and not for American market due to liability

That's interesting.
Those would have been prototypes if only a "handfull" were made.

According to mec, "the chamber capacity of the European R*S is the same as the Pietta LeMat. It will comfortably hold 30 grains and a ball while 60 army and 58 remington replicas will hold five to eight grains more powder without straining the loading lever." --->>> https://www.thehighroad.org/index.php?threads/what-about-euroarms-revolvers.341783/#post-4708234

And IIRC the LeMat's loading lever was sort of a weakness with the design.
That and more complicated internals could lead to a higher price and more dissatisfaction.
Is it harder to disassemble and clean?
I not knocking the design, but exploring reasons why Pietta wouldn't produce it.

Could Pietta's concern about liability with a carbine verses hand held revolvers involve a design weakness of some kind?
Liability doesn't stop Uberti from selling their carbine or Pietta from selling shoulder stocks.

I'm curious where the info. came from where you learned about the prototypes and the Pietta concerns about product liability.
Was it a forum or article, a Pietta exec. or personal aquaintance?
And how long ago were these prototypes made?
It makes sense that Pietta would try to make a prototype since they already make the pistol.
Is there any other reason that you can think of that would make the LeMat carbine a greater liability risk compared to a Uberti Cattleman Carbine besides the US court system in general?

A side thought is that perhaps Pietta would have also needed to provide a sectioned or collapsible ramrod with the carbine in order to load the shotgun barrel in the field.
One that could be more easily carried.
There is a company that makes one.
A video and details are on this page. --->>> https://www.gunadapters.com/ramrod-collapsible/

If someone is very ambitious, Cabela's has a Pietta LeMat Cavalry Model .44/20 gauge revolver for $900 (in-store sales only) as a donor for such a project.

Im not a huge black powder guy otherwise I would have jumped on one that came in on consignment at my LGS for $600. I think they are really neat but that hammer was almost impossible to draw even with two hands.

Why was the LeMatt not used more during the war?? I remember reading that not many were made. It seems like a very formidable weapon on the battle field.
 
A revolver carbine is safely fired with off hand over shooting hand, keeping both away from the gas escape at barrel/cylinder gap.

That is how I usually shoot my ArmaLite AR-7 Explorer rifle and shoulder-stocked C96 Mauser pistol. Both are butt heavy, barrel light. I could see one of the Remington 1858 "cattleman" revolving carbines as semi-practical.

That Lemat carbine appears to me to have a lot of metal out front and I suspect it would be barrel heavy. However, I wonder if the shotgun barrel, being the cylinder pin, blocks gas out of the B/C gap from blowing straight downwrd, creating a safe zone for the arm to support the barrel.

I have thought a cartridge firing revolver carbine with a conventional fore grip might be feasible if the shooter used one of those leather forearm-and-wrist cuffs worn by cowboys in bramble country.


edited due to snidervolley's very valid point about the consequences of a muzzleloading revolver chainfire incident. That has occurred and the consequences to a hand supporting the barrel would be serious. Even though the velocity of a revolver ball from a cap'n'ball cylinder with no barrel confinement is "only" about 200 fps, I think that is about the velocity of a rabbit-killer grade slingshot and it would wreck a wooden forearm and human hand in front of it. That's not counting damage from the powder flash(s). There is a reason designers of muzzleloading cap'n'ball revolver-carbines put a finger spur on the trigger guard for the supporting hand. So far the only semi-successful revolver-carbine with a forearm is the the cartridge-only Judge carbine.

Muzzle loading revolver carbines can never be heald in front of cylinder do to possible chain fires which would take a hand gaurd and your hand down range
