From Walther America's website:

"The Quick Action trigger system: The striker is partially pre-cocked and when the trigger is pulled, the striker is fully cocked and released, firing the pistol."

"Trigger Mechanism: Traditional Double Action with an Anti-Stress Mode
As the first pistol equipped with a firing pin lock, the P99 AS combines the advantages of the traditional Double Action System with Single Action Anti-Stress trigger. The P99 provides the shooter with a user-friendliness previously found only in hammer fired pistols."

"Traditional Double Action
The anti-stress trigger makes the P99 one of the world's safest firearms by preventing unintentional "reflex" firing in stressful situations. The decisive innovation: When the slide is racked completely to the rear upon loading, the trigger remains in the forward position for the first shot; not only in the double action trigger mode, but also in the single action mode. The trigger travel is .551" long in the anti-stress mode (at 4.4 lbs. trigger force), preventing inadvertent firing. On all subsequent shots, the trigger travel is reduced to .314" (at the same trigger force) and this permits firing in rapid sequence, due to the quick reset of the P99 trigger."

"Enhanced Safety
The P99 AS is equipped with a decocking button to safely decock the striker. It acts as an automatic safety and is integrated directly into the slide to prevent snagging on clohing even if the gun is drawn quickly."



All that aside, I tend to prefer the AS trigger. You can fire DA with follow up shots being SA, or you can keep precock the first shot by moving the slide back slightly. No external safeties to mess around with.

Thanks for your reply, I still don't understand the diference between the AS Vs. QA

Phil, the AS trigger is a Dual action/single action trigger. When you chamber the first round the trigger is in Single action which in case of the P99 means the trigger has less distance to travel before the shot is fired. Now if you do the same and press the decocker the trigger is in dual action and the trigger pull is longer therfore making the trigger have more distance to travel before the shot is fired. Now if you fire the gun from the decocked position ( the Dual action) every other shot thereafter will be in single action making the trigger travel less distance ( making it lighter).

The QA does not have a decocker and therefore has the same tigger pull every shot. The distance the trigger has to travel is the same, and the weight is the same every shot.

Hope this helps a little. If your still unclear I think there is a thread here devoted to the different kinds of trigger systems in the general handgun forum.

The QA DOES have a decocker.

I have one, and it DOES have the side button.

The QA is similar to a "Glock" style trigger, and is the same trigger pull for every shot.

IF you have an AS gun, decocked and in DA mode, can you slowly pull back (stage) the trigger and put it into the short reset SA mode?

 

[Kacerdias]

Not sure, never tried it. It would be FAR safer instead to just pull the slide back 1/4" or so until it cocks into SA mode. You'll see the back end of the striker (red dot) protrude from the rear of the pistol indicating that it's cocked.

 

[Shipwreck]

No, but U can cock it, and then have the long DA length with the SA weight

Go read that link I posted - it explains everything.

I have an SW99 .40 (P99 clone) with external decocker, and when the striker is decocked, you can't pull the trigger partially to "set" it to partially-cocked. HOWEVER, if you pull the slide back 1/4" to cock the striker fully, you can pull the trigger halfway back and it will click into a "half-pulled" position. Not particularly useful, but you can do it.

I looked at the Walther P99 and could not decide what to get, and then the S&W M&P came out. I ended up getting one (DAO) since the trigger is supposed to be an improved version of the Walther. I have only fired the M&P though.

The M&P also is pretty easy to work on, if you want a lighter trigger.
