I rewrote the page and turned all of the separate mechanism pages into redirect pages. Somebody had to do it. In keeping with Wikipedia style, arguments about the values of each section should be limited to the talk page. The main article should be edited only for accuracy and content, not to 'put your 2 cents worth' in. Please keep it clean and don't let this article get bogged down with opinions, merits of the systems, etc. I've seen other articles get this way.--Asams10 02:05, 18 April 2006 (UTC)
I have a problem with undated terms like "Pre-set triggers, only recently coming into vogue". As the years go by, 'recently' becomes less and less informative and I'd prefer to see something like 'ca 2005' or whenever, which will stand the test of time.

There is a need for good links in this article as well as a history section. Maybe mention, for instance, that Tomischka patented the first double action only pistol in 1911.--Asams10 02:05, 18 April 2006 (UTC)
"Good links" mentioned in 2006? Shit! It's 2012 now and there are still no good links. Please add some to the main sub-topic "Function" asap.
This is an article about mechanical aspects of firearms and, as such, needs plenty more links to articles regarding mechanics.Themoother (talk) 20:55, 5 May 2012 (UTC)
...and this statement:
After reading this article, I find myself rather confused about the single-action/double-action division, especially regarding the "traditional double action" mentioned. In the SA section, it mentions that most semi-autos use the recoil to bring the hammer back. How is this different from the DA/SA mentioned subsequently? Is this article redundancy repeating itself, or just me failing to understand it? The article seems to imply that the entire subject is rather confusing. Perhaps someone more conversant could make a chart or table, &/or edit the section for clarity? --mordicai. 18:28, 30 October 2006 (UTC)
I agree this section pretty much fails to explain it in layman's terms. "see if there is second-strike capability" is particularly meaningless ! (Does that mean pull the trigger twice and see if it fires again ?)
My guess is that, during continuous shooting, in DA pulling the trigger loads/cocks before firing, whereas in SA firing the previous round loads and cocks the next round for you. OK there are complexities and exceptions, but it might be worth stating it simply first ?

"Second strike" is simply marketing term for DA/SA. The easiest way to tell if a striker fired pistol is DA/SA is the presence of a decocker. DAO has no sear, so the pistol is simply cocking the firing mechanism fully back and releasing it every time. The pistol is always at rest in a decocked state. SAO means that the sear must be pre-set/engaged first to enable the firing mechanism - whether hammer or striker, and the trigger releases the sear to fire it. SAO's cannot fire from an uncocked state. A DA/SA allows for both - firing from decocked, and pre-set states. 65.100.55.74(talk)15:12, 15 September 2021
are you sure about DAO actions being "popular" with police departments? perhaps in the past when revelovers were the norm, but i rarely hear of anything other than sigs (in DA/SA), glocks (pre-set), and the occasional 1911 (SA). these are just my observations, but what do you think? -aaron 141.210.9.36 14:59, 17 November 2006 (UTC)
I tagged the article as unreferenced because it completely lacks in any reliable sources. Kncyu38 08:54, 2 December 2006 (UTC)
I noticed that in the opening paragraph, it mentions the Springfield Armory M6 Scout. However, the link goes to the Springfield Armory Inc. page only. I'd like to split the two, the Springfield armory part going to that page, and the M6 scout part going to the M6 Scout page. However, I'm a wikinewb, so I'm not exactly sure how to do it.

So, if anyone with some writing skills gets bored, here's something to do. 84.129.174.104 (talk) 11:18, 12 January 2008 (UTC)
Hair trigger redirects here, but the term is defined nowhere on this page. I had hoped to see information about what qualifies as a hair trigger, which gun models had them, etc. --Doradus (talk) 06:30, 17 February 2008 (UTC)
The article on the Burr–Hamilton duel discusses this, but raises more questions than it answers. Drutt (talk) 00:23, 2 August 2009 (UTC)
When cleaning up the cite templates, I noticed this didn't lead anywhere. I don't know if the content has moved, or if the URL was entered improperly. Someone who's more knowledgable about this may want to check it out. Howa0082 (talk) 17:53, 5 May 2008 (UTC)
Normally, I would not be so kind as to explain my reversions of IP edits or 'snipes' as I call them, however it seems that this marketing hype is taking advantage of the general public's lack of basic understanding of how a pistol works. "DAK" operation is merely "Pre-set hybrid" with a fancy name. It's the same concept as Glock calling their pre-set trigger a "Safe-Action". DAK is trademarked and there are, perhaps, patents involved, but in operation, it is a simple pre-set hybrid. Feel free to add it as an EXAMPLE of a pre-set hybrid trigger, but don't buy into the hype that there is anything unique or advanced about it. --Nukes4Tots (talk) 15:00, 19 May 2008 (UTC)
Nevermind the single action comment, its in the main article and I fail at reading.
hair trigger are also for competition guns, and are heavily used in the air rifle sports. While not exactly hair triggers (there are limits on how light the it can be in the rules), bullseye, race guns, and similar custom guns tend to have almost zero pretravel and posttravel on light (2-3 pound tops) pulls which some would call a hair trigger. The result of using the set triggers is often a hair trigger as well, and many rifles also have a very, very light trigger. Whoever was going on about them being cheap pistols on par with a SNS or cop killers understands very little about top end competitive shooting sports (unless I misread that part, but it sounded like hair triggers were only for criminal stuff?). Regardless, it does not belong in the main page. — Preceding unsigned comment added by 66.18.49.84 (talk) 18:04, 7 May 2012 (UTC)
Need an entry for "two stage trigger" and maybe whatever you would call a trigger that is not two stage. — Preceding unsigned comment added by 24.112.163.85 (talk) 01:07, 22 December 2013 (UTC)
I merged content from Double crescent trigger and Progressive trigger (and Staged trigger) into this article, placing the section under a general section heading "Variable triggers", a term I made up for the occasion. If any one has a better way of labeling these two mechanisms please feel free to improve the article. Rezin (talk) 22:46, 4 February 2015 (UTC)
I don't see the difference between a progressive trigger and a staged trigger. The article uses nearly identical wording to describe them. It says of a progressive trigger "when pulled lightly, the weapon will fire a single shot. When depressed further, the weapon fires at a fully automatic rate." And of a staged trigger it says "for instance the weapon fires single shots when pulled half way, the weapon fires full automatic when pulled completely back." Are these really different types of triggers? The descriptions sound identical. This should be clarified. Mnudelman (talk) 15:34, 11 July 2015 (UTC)
For some reason, when you search for "Double Action", it brings you here, but Double action brings you to a tiny stub page that briefly summarizes the idea of a double action without really any details or context, and then gives you links to this page. Why not just delete the whole thing, because it doesn't contribute anything that's not already on this page (along with a lot more information to boot)? I would put up a merge request, but still haven't been able to figure out the more technical stuff like that, even after several years. I admit I haven't tried very hard, but sometimes I wish I had....45Colt 10:03, 3 November 2015 (UTC)
Visited this article and there is something major missing: Single-stage v. Double-stage triggers. C'mon folks, what gives? Or am I just missing the obvious. As a rifle shooter of 40-odd years, this omission is incomprehensible. Or, as is more likely, where have I missed the obvious?
Please don't make me rewrite / format the article because nobody has any experience with this, an entirely too common sort of trigger. I'm way too lazy but I can probably muster the energy, needs must.
I'll await replies, prior to digging in with shovel and trowel. — Preceding unsigned comment added by 2601:283:301:1500:1D93:D89E:3F5:542C (talk) 19:22, 15 May 2016 (UTC)
Article needs further clarification on this.
some info from gunsamerica:
"Striker-fired triggers occupy a limbo between single-action and double-action. On the one hand, they’re shorter and most break more predictably than double-action triggers. On the other hand, they are long and heavy compared to just about any single-action trigger.
Newer striker-fired guns feel a lot more like they have single-action triggers (and some are, technically speaking) but with an added amount of takeup to help prevent accidental or negligent discharges by increasing the length of the trigger pull. These combine the better features of both double-action and single-action triggers. They have a long pull for safety then hit a predictable, short wall before they break and fire.
The new crop of strikers is a huge improvement over older-generation pistols that, realistically, functioned more like shorter, lighter double-action-only triggers. But they’re still no match for a good single-action trigger.
Because a safety of some sort must be overcome–whether it’s a double-action trigger or manual safety–single-action triggers only have practical constraints on pull weight, pretravel, overtravel and reset.
The one advantage that striker-fired guns have over DA/SA pistols is weight. Strikers are almost universally polymer-framed, where hammer-fired pistols, given the older designs, are usually metal-framed.
For striker-fired pistols, if a user pulls the trigger and encounters a failure to fire, the remedial action is a malfunction drill–tap, rack, target. Bash the magazine in place, cycle the slide manually and aim and fire again. This doctrine is valid for all semi-automatic pistols, but with double-action-capable handguns, a quick pull of the trigger in DA mode can resolve the problem in a fraction of a second."
