Why did it take so long for the U.S. to adopt double-action revolvers? It seems they stuck with single-action revolvers until 1892 while the British adopted double-action revolvers in 1853, the French and Spanish in 1858, the Swedish in 1863, etc.

Reliability and application. You are probably overlooking a great number of US da revolvers that predate the Colt 1878.

A large part of this is that the Colt company had a very firm strangle-hold on the revolver market in the United States for quite some time, assiduously chasing down and persecuting makers who dared to infringe upon their share by producing similar weapons. Double-action revolvers such as the Schoefield and Smith and Wesson did exist, and were popular in their niche, but Colt simply outnumbered them in production quantity of the basic single-action revolver and therefore commanded the lion's share of the market, advertising, and was able to charge less for the simpler action.

Sure but a lot of the pepperboxes were DA, then the Starr and others working around the Colt patent. Colt had initially dismissed their design as too fragile..

As said above, the early ones were too fragile and that made them unreliable. Why bet your life on an iffy DA revolver, when an SA revolver was far more reliable?

Here's some naive questions from a sword guy.

What are the relative merits of SA vs. DA?

I had one revolver many years ago that had both DA and SA - I had the impression that using the DA option, you could get more accuracy because of less jerk to the trigger on the shot, but it also slows you down.

Are all DA revolvers like that? Or in some do you have to manually pull the hammer back to pull the trigger? I guess that would fit with the famous hollywood image of the gunfighter 'fanning' the hammer. Is that image real or a myth?

Any other differences?

[Patrick Kelly]

I've been a fan of single action revolvers for decades and used double action revolvers in the early days of my law enforcement career. Well, honestly I just like revolvers. An SA revolver is easier to shoot accurately due to the shorter and lighter trigger pull. DA revolvers can also be fired in SA mode, of course, but the primary reason for the DA trigger is safety. The longer, heavier pull requires a much more deliberate effort to acttuate. A DA trigger is also faster since the manual cocking of the hammer isn't required. It does take more training and experience to run one efficiently though.

The SA revolvers popularity in the 19th century US stems from several sources: Colt was primarily a company that produced SA revolvers. Their few DA models were fragile and unreliable. Colt had such a strangle hold on the market, due primarily to Sam Colt's PR machine and underhanded dealings with government officials, that every other company was competing for second place market share. Then, as now, the general public was heavily influenced by the militaries choice of sidearm and Colt's Single Action Army was the primary sidearm for the US Army, with the SA Smith and Wesson Schofield serving briefly as a substitute standard, Other companies such as Smith and Wesson offered DA revolvers, but their trigger pulls were so atrociously heavy that accuracy was difficult if not impossible to achieve. Colt's SAA also features a very simple mechanism that could be made to fire even with several broken parts, an important thing on the 19th century american frontier.

If you are talking about the American Military adoption of DA revolvers there were three big detriments to their wide adoption:

• Smith & Wesson had the early patents on DA and their Model 1 was strictly small frame and low powered
  
• Smith & Wesson didn't have the manufacturing capacity to accommodate general gov't contracts
  
• The Gov't had already invested in tens of thousands of Colt SA revolvers, both ball and cap and later cartridge conversions so it was't cost effective to make a wide change in the years immediately following the American Civil War.
  

In 1870, however, S&W released the Model 3, a large frame .44 cal. DA revolver which the Gov't quickly jumped on and issued a contract for making it the first cartridge handgun and DA revolver in gov't service. This contract was concurrent with a contract to Colt for .45 cal. SA cartridge revolvers. In 1875 the Model 3 update "Schofield" was accepted by the gov't using a shorter .45 cal round than the Colt. This caused problems for the S&W in service though because the large stocks of .45 Colt cartridges wouldn't work in the .45 S&W while the Colt revolver could use either cartridge which eventually led the Army favor the Colt.

In civilian hands the DA Model 3 was very popular, especially on the frontier where the ease of DA was a big advantage in the heat of a fight. They were favored by many famous frontiersmen from cowboys & outlaws the lawmen that hunted them, regardless of what Hollywood would have you believe--which almost always shows everyone using the Colt "Peacemaker" .45. Billy the Kid, Jesse James, John Wesley Hardin all used Schofields. So too did Virgil and Wyatt Earp and Pat Garret among many others.[/list]

Simple preference might also be a factor. I like single action revolvers, and dislike double action revolvers. The main reason being deliberation of action. I have never fired a single action revolver unintentionally, but have fired a double action revolver unintentionally, fairly quickly following a deliberate shot. Of course that is more likely a hair trigger on a particular gun, but the experience is part of the reason for my preference.
In the US, as mentioned above, waste of ammunition or repairs required for more complex actions I'mean sure we're also part of preference. A fancier tool or piece of equipment doesn't do much for you if it isn't working reliably.
