Auto-Revolver Concept for L9OBL by SgtMuffin Auto-Revolver Concept for L9OBL by SgtMuffin
This is an Auto-Revolver concept that I proposed to [link]

Nothing spectacular art wise but it gets the point across.

It is a gas operated revolver, using gas to cycle the cylinder and also re-cock the hammer so that you do not have to pull back a full weight. Two version:
The top has a hammer like all conventional revolvers, but uses gas to cycle the cylinder and to reset the hammer to full cock.
The bottom has a bolt which would allow for removal of the Main Spring that is used to force the hammer down on the primer of a projectile. Makes the revolver look more like a Semi-Auto Self-Loading Pistol with a cylinder, which coincidentally is just like the 10mm pistol from Fallout 1: [link] (You have to look very closely).

These are designed for use in the FO:E universe, but feel free to use them (not that anyone probably will) elsewhere.

i think it would be simpler for the gas tube to impinge directly into the hammer, or the piston to be one solid piece from the gas port to the point of contact on the hammer itself. maybe a gas tube impinging onto a hinged transfer rod which transfers energy to a cam at the base of the hammer?

I didn't really think much into this. It was just to prove a point, not to be a fully working design.

But isn't the intellectual exercise part of the fun?

Not when I have more important things to work on.

nothing is more important than that, which is the intellectual exercise of engineering :3

But I do agree, intellectual exercise is a very important thing that not enough people take part in these days.

Would just like to add that "automatic revolvers" are an actual thing

Mateba Model 6 Unica

Your idea, is actually not viable due to the combustion gas loss from the cylinder to barrel mating surface. Where as the purely recoil based operation of the Mateba is much more practical.

Yeah I know about the Mateba, and it would be possible.
the Mateba is very problematic with its recoil action. If you don't have a big enough load you will not get a cycle, which means you need to use loads over .357, you also have the problem of weak handed people not being able to cycle the gun a lot of the time. This is pretty much why the Mateba was never even looked at for service.
A gas operated revolver is possible, you would know of the Nagant 1895, when fired the cylinder moves forwards and creates a seal with the barrel, that would allow the gas to successfully pass into the piston and reset the action. Yes, I didn't draw it onto this picture, but I had it in mind while drawing (as this was just a simple idea to shoe L9OBL) and didn't add it because I did not expect Gun-nuts (like myself) to come on here and pick out the flaws I didn't include. :P

Thanks for the input anyway, shows that I will have to go into greater lengths of detail next time to avoid this.

Not really trying to nitpick, lol. I just deal in revolver a lot. Mainly mid 1850's through early 1900's.

Yes I'm aware of the Nagant, as I am also aware of the chamber seating issue making it worse than the Mateba in my opinion.

yes the .357 is a larger round, however until you fire a Mateba loaded as such and realize just how little kick it has, you won't understand that misconception. Yes it has its share of jamming issues, however consider that we're talking about a 'revolver' being 'semi automatic' and that the point is mostly futile.

Personally, the engineer in me thinks that the recoil based option seems like the better choice compared to trying to maintain a metal to metal seal on a revolving cylinder, under compression forces.
