Merits and Misunderstandings of the Double Action Trigger

The success of the Glock family of pistols and the numerous variations on the polymer-framed, striker-fired theme that exist on the market today has led many to view the concept of a double action trigger as a bit of an anachronism. Jeff Cooper maligned double action semi-automatic pistols as “crunchentikers” many moons ago and the stigma has kind of stuck with them ever since. Folks who bring up that term today often forget that Cooper was involved with the 10mm Bren, which happened to be a double action pistol. The cool kids in the gun world shot custom 1911 pistols, often turning their nose up at the very idea of a double action auto, and those who embraced plastic went to Glocks fairly quickly after. As any simple Google search will demonstrate, some Glock and 1911 fans are often quite vocal about their preferred blaster and tend to proselytize fairly aggressively with a fairly good record for conversion. As a result, there’s not a lot of people out there who really understand double action triggers, how to run a double action trigger well, or what benefits they bring to the table.

I’ve come to appreciate the benefits of the double action trigger with training and experience

By the mid 1980’s it was clear to anyone who had their eyes open that the revolver’s days as the workhorse of law enforcement were over. The U.S. military had just adopted the Beretta 92 pistol. A lot of departments who had issued revolvers saw the double action automatic as likely to be an easy transition for their officers and so they bought up the Beretta as well as offerings from Sig Sauer, Smith & Wesson, and to a lesser extent Ruger. Even Colt saw the writing on the wall and made a few attempts at producing a double action semi auto. (Google the Colt Double Eagle…ain’t that a trip?)

Unfortunately it wasn’t an easy transition for everyone. Police revolvers were often issued with very small grip panels that were less than ideal for officers with big meaty paws but happened to be a positive boon for officers with smaller hands, like the many female officers who were just coming into the profession. With the small grip they could get their hand around the gun well enough to get decent leverage with the trigger finger and shoot well enough to qualify with minimal instruction. A semi-automatic pistol with a double stack magazine didn’t allow for the same flexibility in gripping the gun, which often left the officer struggling to get enough leverage on the trigger to work the double action pull properly. We like to think that “back in the day” everybody was an expertly trained marksman, but the truth is that police firearms training “back in the day” was typically poor. Then as now there were some excellent programs and instructors, but by in large the typical police firearms training was mediocre at best and it led to some pretty heinous results. Officers stuck with an ergonomically sub-optimal sidearm and poor quality instruction struggled to use the new pistols well and improvised methods of getting the job done well enough to qualify that didn’t serve them as well in the real thing. Often instructors sought the path of least resistance and would sometimes even encourage officers to cock the hammer of the pistol as they drew it, voting “present” on the concept of teaching the DA trigger. I’ve met more than one police officer who was taught to fire his first round into the dirt to get past the DA trigger pull and then start fighting with the gun in single action mode.

All of this combined with an ever growing acceptance of an Austrian pistol that shipped in what looked for all the world like a Tupperware box (Seriously. Google Glock box and you’ll see something you’d expect to pack leftovers in) started to give the double action trigger a bad rap. Folks seemed to forget that having a longer, heavier trigger pull for at least the first shot on a sidearm used in supremely stressful situations by people that were largely unfamiliar with functioning at that level of stress tended to cut down on accidents with a gun in the hand. (It certainly didn’t make it impossible, though.) That longer, heavier first shot tended to be more forgiving of handling mistakes like reholstering with one’s finger on the trigger. The typical hammer-fired DA gun also didn’t require a trigger pull to disassemble the weapon for cleaning. Many an unintentional discharge has happened when someone has been attempting to break a Glock down for cleaning. Proper procedures will certainly prevent that from happening, but when you run an organization with dozens of people in it you can be certain that there will always be a percentage of people who don’t follow proper procedures.

Contrary to all this accumulated lore, it is most definitely possible to run a double action pistol well. A few weeks ago I mentioned Ernie Langdon had teamed up with Wilson Combat to help them get their Beretta custom services off the ground. In that article I mentioned that Mr. Langdon had won a couple of championships with a Beretta. In truth Mr. Langdon’s contributions were a bit more important than that. Around the turn of the millennium (just hearing that phrase in my head makes me feel really old) conventional wisdom held that you just couldn’t get good results from a DA trigger. The handgun sports were all dominated by Glocks and 1911s. Mr. Langdon had spent years running the USMC’s High Risk Personnel program where he learned how to use the Beretta 92/M9 very well. He knew the Beretta so well, in fact,  that he ended up going to work for Beretta as a rep to the military and law enforcement. Mr. Langdon started competing in the shooting sports with a Beretta and recruited other shooters for the company. More importantly, he started winning championships with the Beretta, putting a big dent in the idea that you can’t run one well. After leaving Beretta he went to work for Sig and won with their guns, too. So much for the DA sucks theory…

In truth you can use a DA semi-automatic very well if you get some instruction from somebody who knows how to use one. Mr. Langdon is getting back into offering classes these days and he’s even leveraging the power of the web to spread knowledge about running a DA pistol properly:

I’m not trying to argue that people who like their Glocks and shoot them well should drop them right now and go buy themselves a hammer-fired DA gun. If you like what you’re shooting, rock on. If you’ve been influenced by the conventional wisdom which argues that the DA trigger is vestigial or even counterproductive, hopefully you’ll be open minded enough to reconsider.

Personally speaking, I prefer guns with a double action trigger to striker-fired pistols. The gun I carry daily is a H&K P30 with the double action only LEM trigger system. When I first got into shooting I would have laughed at anyone who told me I’d be carrying a DAO 9mm pistol. I mean, come on….I’d read Cooper articles for years. Thankfully I was exposed to solid instructors who challenged some of my preconceived notions and showed me what you could really do with a good double action handgun.

So to borrow Mr. Langdon’s phrasing, fear not the double action shot. Heck, if you approach it with an open mind and use the tips Mr. Langdon mentions above, you might even like it!


  1. Colt Z40, made by CZ circa 1998. Don’t forget Ben Stoeger using a Beretta, and a bunch of people now winning in USPSA Production using the CZ SP-01.

    1. Stoeger will be the first to tell you that the triggers on CZ Accu-shadows and Tanfog’s are nothing like a stock Beretta trigger. Much harder to shoot well.

      1. I would agree on the Shadow’s as they do not have the firing pin block. I have never shot a 92 or a Tanfoglio, just my slightly modified 75B. I have been looking around to see who uses/wins with a Sig DA/SA model like the 226. I have been looking for a new DA/SA gun to compete with.

        1. You will be looking for a while. Approximately 0 super squadders use Sigs that I’m aware of. Only guy I know that does use Sig is Max Michel, but he’s sponsored by them and uses their 2011 stuff anyways (not DA/SA)

          1. So the viable DA/SA guns to use are Beretta, CZ, and Tanfo? Maybe I should just stay in Single Stack..

  2. One piece of advice the Bren Ten folks took from Jeff Cooper was to make their pistol capable of being carried or stored cocked and locked, like the CZ 75 It made his “crunchenticker” complaint passe’.

    Best of both world’s for the most people.

    I don’t understand why so few pistols marketed these days allow for the choice.

    1. The old Bren didn’t have a de-cocker, which required the user to lower the hammer manually to get into the DA mode. A practice Old Man Cooper frowned upon with the 1911 and Condition Two, for good reason- I would NOT want to be the guy lowering a hammer manually on a loaded weapon before re-holstering in the adrenaline-shakes phase after a defensive action.

      1. ST

        I’m pretty sure Cooper would have advised that guy to leave the hammer alone, thumb up the safety and holster the pistol.

        Look, i understand the argument and people who want a de-cocker seem to have won it. I’m just commenting.

        It’s why guys like me with shorter than average fingers still prefer Hi Powers and 1911’s.

        It helps explain why most of the other half of the population called women don’t buy a lot of full size Berettas and Sigs.

        And I think it goes a ways toward explaining the increasing popularity of striker fired/trigger safety pistols over DA/SA de-cockers.

        And just to be clear it isn’t the DA to SA variation in pull that’s the problem, it’s first shot trigger reach.

    2. Because it requires another control to do so.

      DA guns need a decocker. Most DA guns simply make the “safety on” position do the decocking. To make it usable as DA or cocked and locked that is not an option. So either another control has to be introduced (expense, can affect ergonomics, and increases complication), or a third position has to be added to the safety that does the decocking, which has it’s own issues because manipulating the safety under stress (which you need to do if carrying cocked and locked) now means you’re operating a control that can either unsafe the weapon (as you intend) or decock the cocked weapon (definitely not as you intend) in a high stress moment.

      Not saying that any of the above kills the idea or is insurmountable. There are good guns that manage it very well. But it’s also easy to see why a company might just take the tact that if you want an SA gun you’ll buy one, and just worry about making their DA guns as they can for DA usage. Many do exactly that.

  3. If that photo of the P30 is yours… I see what you did there. Nice.

    Good videos, too. I’ve always been partial to DA autos, so this was great advice to hear.

  4. I don’t really think that HK’s LEM trigger is a good example of a DA trigger. Since the hammer is actually two parts, one of which is pre-cocked by racking the slide, firing the LEM is more like an SA, only with the longer travel of a DA prior to the break. I love the LEM and carry my P2000sk with that trigger variant, but it is really more of a hybrid.

    In the USP line, HK does offer a true DAO trigger. I can’t remember the variant number, but it does not seem to pop up very often. As far as I know, the DAO versions of the P30 are only available in Europe.

  5. A merit I would add to the DA/SA trigger would be the following:
    1. Ability to thumb the trigger back into the holster decreasing the chance of a negligent discharge. Certainly the ND issue with striker pistols can be dealt with training(fast out, slow in) but in my 20 years I can remember 2 or 3 times going back cocked(that doesn’t feel right) and stopped. If something was to get in the trigger well, I would get the feedback on the thumb.
    2. Could be a myth, but I think the heavier DA trigger might limit/slow the number of rounds discharged under stress. I don’t have the statistical facts to back that up on hand but the couple I personally looked into never emptied their magazines while reading news reports of northern large cities emptying magazines in short order. Of course the ability to discharge large amounts of ammunition in short order at close range is also positive feature when its has to be done…

  6. The fnp and fnx pistols allow for the choice. Outside of the supertactical .45, why couldn’t you use one of those?

    1. I have actually considered the FNX. I have never seen anyone compete with one, nobody I know owns one, and there is nothing in 300 miles to rent one to try. You know how the internet is, but if it breaks, you need super secret tools to fix it or send it back to FN. Those are my reasons. Am I wrong?? Heck, I have thought about getting a Tanfo too, and I know those that shoot them, but all have said that EAA just plain sucks if you need a part. Shoot it enough and you will need a part.
