Idea to create a new revolver with a modified action

[Techsent]

Hi there folks,

I own the 629 classic .44 revolver. Great gun! Here's an idea to create a different type of revolver....

It would be such a great feature if a revolver could auto re-cock the hammer after each shot (when releasing the trigger, the cylinder would advance which would also auto-cock the hammer) so we would essentially be shooting single action all the time while still using a double-action concept but in reverse. This approach would immensely help keep the gun stationary when pulling the trigger.

There is one massive problem with this, particularly in revolvers with more felt recoil. Namely, the accidental double tap. Experienced users might be able to figure this out, inexperienced users would likely trigger a second or even third shot.

Webley-Fosbery Automatic Revolver was made in England over a century ago. Read up on it. Interesting gun but not too successful, especially in WWI.

What could potentially work would be something like the double action Kellerman system, where the revolver would function from a half dash cocked position with a lighter trigger

hmmm... Good point Rocketmedic40. Maybe the trigger can also move forward back to default position (after moving the cylinder and cocking the hammer) then the user would have to pull the trigger all the way back again to fire...? So when you would shoot your first shot, you would have to manually cock the hammer just one time (or double tab just one time at the beginning) then fire and the rest of the shots are single action (meaning hammer is already cocked).

Yes. something like this. anything to offset the force needed for the trigger pull.

Thanks Erik. I'll check that out.

Without recoil assistance, a return spring strong enough to cock the hammer would also increase the trigger pull.

I fail to see any advantage over a modern semi-automatic pistol. That said, I like the relatively light trigger pull of a Kellerman action, with an external hammer and the added safety of a DA trigger.

 

[Neumann]

You can reset a Kellerman action by pressing the trigger twice. However, you can execute a second strike with a normal DA trigger pull (8-10 lbs) In normal operation, recoil resets the trigger with the hammer in sort of a half-cock safe position and a 4-5 lb pull..

maybe but if the return spring does all the work mechanically as the trigger moves back to position then pulling the trigger should be free flowing with no tension at all.

very popular in old mystery novels

Sorry brother your about 120 years too late. nihil novi sub sole

The Webley Fosbury is an amazing revolver. The recoil impulse is indescribable with so much of the gun in motion, cylinder turning and the top half moving. I always think when I shoot it, along with my US Krag, how was this built back then. My most grail gun.

Webly-Fossberry made the exact gun you want..........100 years ago.

Mateba Model 6. Italian built. I shoulda bought one when they were on closeout!

If you ever shot a well tuned Smith & Wesson revolver double action you would find the automatic cocking feature unnecessary.

 

[diecidecimi]

Of course it is possible. I am italian, and here several decades ago Mr. Emilio Ghisoni, a Gun lover engineer , designed and produced a bunch of innovative firearms, well known and extremely sought after , today. MT1, 2006M, MTR8, Grifone and the mythical 6Unica.
The Mateba (Macchine TermoBalistiche) was the factory he founded. The name is semi-serious: he stated that firearms are thermo-balistic machines, when his factory previously produced machines to make pasta.
The 6unica is an autorevolver, extremely efficient and smart. The barrel, as every revolver designed by Ghisoni, is on line with the lower cylinder chamber to reduce recoil, and the upper of the Gun is sliding backward as a semiauto pistol, recocking the hammer.
Too expensive to be popular, the project was eventually dismissed, but these days every collector is drooling on it, and prices skyrocketed over 5k, even 10k sometimes.
Here my nickel 6unica .347 magnum , 4" barrel. Barrels vary from 2" to 8", often compensated, and you can easily change them simply unscrewing the shroud and the barrel. Calibers are .357 magnum, .44 magnum and .454 Casull.
The last Ghisoni revolver was the Chiappa Rhino you all well know, I guess.




Here a demo of the semiauto shooting (from the web)

Interesting idea, but I does't seem very practical. It would essentially be a semi-automatic pistol with a cylinder that would be slow to load instead of a magazine. Don't get me wrong, I love shooting my revolvers at the range. However, I seldom conceal carry one due to the bulk of the cylinder and very limited round capacity. My 9mm Masada Slim Elite is only an inch wide and carries 13+1 rounds.

Been done ... 100 years ago !
Lots of interesting things have been tried ,,, I find Firearms History Books to be very fun and informative ...
Some early and very strange ideas have been develpped , tried and found wanting ,,, the auto cocking revolver just didn'tmake the cut ... but it is a fun and interesting story of firearms development ... and ... it did work !

Sure, if you disregard the rules about conservation of energy established by Newton, Hamilton, and Einstein.

From Wikipedia;
The Webley–Fosbery Self-Cocking Automatic Revolver is a recoil-operated automatic revolver designed by Lieutenant Colonel George Vincent Fosbery VC and produced by the Webley & Scott company from 1901 to 1924. The revolver is easily recognisable by the zig-zag grooves on the cylinder.
