In a minority- I like DAO pistols

Deanimator said:

1. REAL "DAO" permits a firing stroke without resort to any action besides pulling the trigger, and activating grip safety (if present).
2. The U.S. government "considers" a lot of things, including that an imported Kalashnikov type rifle with one fewer American made part than another identical Kalashnikov rifle is somehow "evil" and prohibited.
3. I've never heard Glock refer to their trigger mechanism as anything other than "safe action".

You and I are in the small minority of purists who believe a DAO trigger mechanism requires the trigger to perform the entire actions of charging and releasing the firing mechanism. Most people -and manufacturers- use DAO to describe designs in which the trigger must add to the power of the firing mechanism before releasing the firing mechanism.

A Glock trigger satisfies the double-action definition by performing two actions: (1) preparing the firing mechanism to fire, and; (2) releasing the firing mechanism to fire.

A Glock has no way to fire in single-action mode as Gaston Glock explained in his patent application (page 4, line 48): "The pistol is therefore always uncocked or partially uncocked." The Glock trigger moves the striker back "far enough that it will ignite the cartridge that occurs with the continuance of the trigger pull." The patent application makes it clear (page 2, line 54) "the force of the partially loaded firing-bolt spring or hammer spring is insufficient to fire a shot" and (page 2, line 64) "The cocking for each shot is effected by the trigger."

A Glock trigger moves the striker from a position in which it has insufficient force to fire a shot to a position in which it does have the force needed to fire a shot; that certainly seems to fit the generally-accepted definition of DAO.

The “Safe Action”® System is broadly misunderstood to be a type of trigger mechanism when it is only a system of safeties.

GLOCK pistols are equipped with the “Safe Action”® System, a fully automatic safety system consisting of three passive, independently operating, mechanical safeties, which sequentially disengage when the trigger is pulled and automatically reengage when the trigger is released.

Regarding those guns that still require some slide retraction to partially-set a hammer, the forensics report on the Kel-Tec PF9 used in a high-profile defensive shooting in Florida identified its action as "hybrid double-action."

On a related note, its designer (George Kelgren) had people primarily used to the .38 snub in mind when he designed the Grendel P10 .380 pistol. The idea was that many users, particularly LEOs seeking a backup gun, would like the simplicity of the snub revolver, but thinner, lighter, and with more ammunition. There was to be no safety lever or magazine release to be accidentally actuated, especially during ankle carry. The DAO trigger was so that the gun would be fired in a manner similar to that used with a revolver carried for the same purpose.

The gun's lackluster quality, along with the limited size of the company and its marketing resources, prevented the product from succeeding.

Deanimator,

Your friend must have messed with the trigger or it was a lemon. The BERETTA 92/96d models had a large amount of sales with the trigger being one of the reasons for those sale (reliability and accuracy were the other big reasons).
I have several BERETTA 92/96d models and all have good to very good triggers. My agency issued the 96d model for about a decade and very few revolvers had a DA trigger that smooth or light.
I also had a WALTHER P99AS model and the double action on it was also excellent and as good as any factory revolver trigger I have come across.
I will say that many of the new revolvers have improved triggers compared to those made in the 1970's and 1980's, but the BERETTA is a match for almost any revolver out of the box.

I like a positive thumb safety. And an accurate first shot and every subsequent shot.

Ever wonder why DA only pistols are never seen at an accuracy match?

Horses for courses: Of course. You're right, but we saw some astoundingly good double action shooting back when PPC with revolvers was the tactical-practical game in town.

It's something people can learn to do, to aim at x rings with DA handguns. That level of accuracy is not ordinarily required in personal defense but it is nice to know it is possible, given enough practice ammunition.

I also rarely see dedicated match guns being carried for personal protection.

You could also ask: "Ever wonder why you see so few SA pistols with safeties in the holsters of those that carry a handgun for a living?"
