Do you want a manual safety or do you not?Regardless, remember that practice is the most important, and is the only true way to become fully proficient with your weapon of choice.I was reading the article about SA/DA pistols in an effort to understand the differences and why! The long, multi-pound trigger pull of the double- action mechanism serves as its primary safety, in addition to internal safeties to guard against accidental discharge if you drop the weapon.When carried safely, single-action semi-autos require the safety to be disengaged before they can be fired. They are called “single action” because only one mechanism – the release of the ha… Since the trigger pull performs just a single function, the trigger pull on a single action firearm is light and short.In double-action operation, pulling the trigger performs more than a single function. Recocking the hammer for the next shot is automatically performed by the operating mechanism. The types of action (single/double) vary based on the function performed by the trigger.In a single-action, when the trigger is pulled, the hammer is released, causing the cartridge in the chamber to fire. If you’re new to guns, you’ve undoubtedly been hearing a lot of words and phrases and firearms-related terminology that you have little to no knowledge about.Today, we’re going to talk about the terms single action and double action (as well as DAO, or double action only, and hammer fired and striker fired).If you’re experienced with guns already, then you probably already know what each of these terms mean (or at least you should), and you can quit reading now.
Single action and Double action differ. Most single-action safeties function by blocking the hammer so it will not fall if the trigger is pulled or by blocking the trigger itself. Umm, they don’t. Nonetheless, the longer trigger pull also makes them safer, plus the exposed hammer reduces the chances of the weapon snagging when it is drawn from a holster or pocket.The originally semi-automatic pistols were hammer fired, single action only weapons. All semi-automatic firearms perform the same three functions after you pull the trigger: the gun fires, the spent cartridge ejects and the next cartridge loads into the chamber. A single action only vs. a double action/single action or double action only pistol, for instance, can have huge implications on your training and proficiency with your weapon. Why would I want something other than pull the trigger and fire?
The hammer has to be cocked in order for the weapon to fire, but the slide cycling meant that the hammer would be cocked for you so you wouldn’t have to cock it yourself.Single action only pistols like the Colt 1911 have a very short and crisp trigger pull, which makes them easy to shoot accurately but also more dangerous to carry (the 1911 or Hi-Power pistol should only be carried with the safety engaged, for instance).Modern day striker fired pistols also have triggers that are very comparable to SAO guns. The German Walther, introduced in the late 1920s, was the first double-action model.

The hammer remains in the down position. Many double-action semi-automatics designed for law enforcement or military service employ no external safety. There's a saying: a single-action wins marksmanship trophies but double-action wins gunfights.Gus Stephens has written about aviation, automotive and home technology for 15 years. Since 2001, we have provided the latest in gun rights news, tech reviews and product information.Single Action vs. Early semi-automatic pistols such as the Luger and the Colt Model 1911 were entirely single-action. Now, finally, let’s talk about what these terms really made. Most SA guns like the Colt Peacemaker have a loading gate that allow the user to only eject and load one round at a time, which can be a major bummer in a self-defense situation.These guns therefore have a very long trigger pull, which can make them difficult to shoot accurately. A mechanism is the trigger, hammer and safeties considered as a single unit. If it flies, drives or just sits on your desk and blinks, he's probably fixed it. On the other hand, the shorter, lighter trigger pull of a single-action mechanism is more conducive to steady aim and accuracy than the long, heavy trigger pull of a double-action.
