Why do they call it a DA trigger?

    Regarding the M series, why do they call it a DA trigger?

    I am new to steyr handguns, and love my M9 thus far, but I am curious about the trigger system. Clearly it is not a tradional DA or DAO trigger. The trigger wieght is impossibly light and short to be actually drawing the hammer/striker back. This is obviously done during the cycling of the slide, which would make the M series a SA trigger, or something similar.

    I hear it described (including by the manufacturer) as a double action trigger, but this can not be the case, at least not in the traditional sense. So what is the explanation?

    Racking the slide does not FULLY precock the striker. IIRC it precocks to approx 72%(or there abouts), this is said by Steyr, to not be enough to ignite a round should the sear somehow slip or malfunction. Only by virtue of pulling the trigger rearward to complete the cocking action can a round be fired. Similar to the Glock, but having more precock, hence a better trigger(in my opinion.)

    I've never liked the description as a DA trigger either. It's more like a SA trigger, they need a new term, glocks and steyr's are unique trigger systems as is the old SW sigma etc....

    if you have a round chambered you can decock a steyr , and then recock it by pulling the slide back about 1-2 inches.

    Edit: do not try this with live ammo . Steyrclub nor any of its staff or members can or will be held responsible for improper firearm handling or firearm misuse.

    How do you "decock" a Steyr (M9)?

    That makes sense. Agreed, a new term is needed. I purchased the gun expecting what I had heard described as a "very light DA trigger" and after firing it, decided that there was no frickin' way it was.

    Anyone done any testing on the idea that a sear release will not ignite the primer? Just curious.

    I have already discovered the ability to reset the trigger by slightly moving the slide. I was not aware of the ability to "decock" in that manner.

    yes it is possible.. try this without any ammo nearby... pull the slide back as you normally would to engage a round into the chamber."even no there will be no round in the chamber" now the trigger is set as normal.. ok now pull back on the slide somewhere between 1/4 to 1/2 inch while lightly depressing the trigger.. wahlah.. lil click and poof your steyr is now decocked. try it dry over and over again prior to attempting anything with live ammo in the barrell. i would also reccomend any experimentation be done at a range with the barrel pointed downrange. be carefull . just fudge around with it with no magazine in it.. you`ll see what i mean..

    Makes sense. I can't really think of a good reason to ever do this with live ammo chambered anyway. The likelyhood of firing out of battery is very, very low, but why mess around. Just remove the mag and eject the round first.

    Yea, I agree, I don't see any situation where I'd want to do this manufer (wrong spelling). Especially with a safety. Just remove the round and mag pull the trigger and put the mag back in............we dont have a spell check here do we????

    Safe Action triiger systems w/ preload...

    glocks have them, steyrs have them, Walther p99QA's have them, Sig DAK trigger system is basicly the same, old S&W sygmas have (don't know, but suspect new M&P's do too).


    Here's the catch though, Springfield XD's thought they had them, or at least they marketed them as such. But the BATF determined them to be SA triggers! Hence why in IDPA they are in ESP divission while the rest of those are in SSP.

    So for all those who cry "steyrs aren't DA" (ala, cornbread) I say, why does the BATF say they are?

    Is that a big stink in IDPA?? Or should I say with the Springfield boys?? Not having a Springfield, I wonder what the difference is?? less initial takeup on the trigger pull?? I keep getting more used to my Steyr pistols, actually took the 1911 out yesterday and didn't enjoy it as much as i used to........but had a blast with the M9................ 8O

    I think the ATF ruling had to do w/ the fact that it would set off a primer if released; ergo it was deemed a SA trigger.

    BUT, that is what I was told I didn't read it anywhere.

    I do know the XD's were originaly imported and marketed as DA, but the ATF made them stop calling the trigger DA.

    Shooter, The deal in IDPA is that Steyr, Glock and most other stock double action factory pistols can compete against each other in Stock Service Pistol (SSP) while the Springfield has no choice but to compete against the customized single action pistols in Enhanced Service Pistol (ESP). They are just not as competitive in that division as they would if they had been allowed in SSP.

    There is quite a bit of modification allowed to the gun in ESP while very little can be done to enhance an SSP gun. This puts the box-stock XD at a disadvantage.

    After reading this and checking online a little, I now understand the distinction, but as for the BATF ruling, I'd hardly consider that gospel from a technical standpoint. They may call it a DA, but clearly it is not in the traditional sense. There is obvious folly in looking to a government beurocracy for guidance on just about anything.

    the gun range i frequent routinely refers to the glock action as a one and a half action gun. (the half being the 50% precock) this can be very confusing to newcomers but might more accurately describe the action.

    this would make a steyr a 1.28 action gun because we're 72% pre-cocked and that much closer to striker release. which can support the idea that the steyr is in fact closer to a single action than a double action.

    however, pulling the striker rearwards before it strikes is the definitition of double action.

    by that definition though there would be very few true dual action striker pistols. the only one i can think of is the FN Forty Nine

    Walther P99 AS action. True double action striker fired with second strike capability.
