Use the Reset Luke….

Posted 06-30-2010 at 15:48 by Butch

The Bureau of Alcohol, Tobacco, Firearms, and Explosives says that the Glock ‘Safe Action’ trigger is a double action only (DAO) trigger. OK, but it is so much more…..simply put, it allows the shooter to use the trigger either way, as a DOA trigger or as a single action trigger.

If you start with the trigger all the way forward (I guess that’s the only way it can start huh?), and pull it straight through all the way to the rear to fire the gun, you just pulled it ‘double action’. Pulling the trigger that way did the two things required to fire the gun, it finished pulling the firing pin all the way back to what could be called it’s fully cocked position, and it released it to fire the gun. It also deactivated the three passive Glock safeties, but they aren’t what we’re talking about here.

Due to the time and movement it takes to pull the trigger from front to back, the shooter has more opportunity to move the sights off target from the start of the pull till the shot fires, and with a Glock, ‘hitting’ the reset point near the rear end of the trigger movement can cause the shooter to pull the shot off target all by itself. Also, moving the trigger all the way forward and all the way back for each shot takes time, unless you’re a *very* good shooter, you’re shooting slower than you need to.

The other way to use the Glock trigger is to ‘Use the Reset’. Again, one must start with the trigger all the way forward, but instead of simply pulling the trigger all the way straight through to the rear to fire the shot, you just pull it back (stage it) to the reset point, and from there you apply steadily increasing pressure to it until the shot fires….just like any single action trigger.

When the shot fires, the slide opens, the empty case ejects, and the slide moves forward to chamber the next round…..and it all happens before you can let the trigger move forward….when the slide closes, you are still holding the trigger to the rear, and this is the key.

At this point you *don’t* let the trigger move all the way forward, you just let it move forward to the point where it resets, the ‘click’. The click is made by the connector as it snaps back into position behind the rear end of the trigger bar as you let the trigger move forward. At this point all you need to do to fire the next shot is squeeze the trigger again….in a single action mode, and continue to repeat until you are done firing.

Yes, to use the reset in this manor takes some training, a conscious effort to make the trigger control a habit that you can do without having to think about it when you’re shooting….lots of repetitions. Start with dry firing (no ammo). Stage your first shot and squeeze it off perfectly, now hold the trigger to the rear and rack the slide enough to reset the firing pin, get back ‘on target’, and then let the trigger move forward slowly till it clicks at the reset point. Now you can squeeze off the next shot….single action.

It is my very experienced opinion that using the reset to shoot the Glock as a single action is the only way to do it, it’s easier to be more accurate, and it’s faster. Use of a NY spring makes it more difficult to control the trigger movement well, both forward and backward movement.

Use of a NY1 trigger spring with a 3.5 connector to best simulate a DAO revolver type trigger pull is probably the best use of a NY trigger spring, but I’d be right surprised to find anyone using such a setup to win the Matchmeister prize at a GSSF match.

    Great clarification on this confusing issue for me. Thanks for pointing me in the right direction!

    I completely agree with the technique described in your great post, however, I'm wondering how ATF would describe Glock's trigger as DAO if DAO trigger on self-loadin pistols should alwais have a second strike capability ... ?

    That's a pretty big if!

    The need for a second strike capability is just a matter of opinion.

    Some folks think a second strike on a primer that failed to fire on the first try might make it fire the second try.....others think it might be a waste of precious time when a fresh round could be getting racked into the chamber instead. Depending on why the gun failed to fire on the try, I think they both *might* be right!

    The Military had a prerequisite requiring a double strike capability for the M9 trials, but there is no rule/regulation/law that I'm aware of that requires it for a gun to be classified as DAO.

    I agee, but in my understanding DAO should be just as it is : DAO, on the other hand, Glock's trigger is acting as a SA if you have a missfire ... I understand the point with the matter of opinion, but if we have a DAO trigger, misfired round will not change the way the trigger operates... I am not concern of the quicker technique for dealing with missfired round, you are absolutely right about it, but my point is strictly about the action of the trigger... I think second strike capability is a natural property of DAO trigger, regardless of how we clear the bad round in the chamber...Why should I not have the sec. strike cap. on a Glock trigger ... ? What is the advantage for someone, that is not enough trained to clear the gun, like ... 60% probably of all that legaly carry a gun...
    It's getting some how academical but it is interesting why someone would determine Glock's trigger as DAO, basicaly considering only the process before cicling of the gun ...
    Best regards.

    Double action has nothing to do with second strike.
