My buddys smith and wesson needs to be racked before the trigger becomes "active" (IE the hammer drops). Yet on my sig p226 the hammer will always drop regardless if the the gun is racked. both guns are DAO. So what am i missing here? Whats thr term and or feature that the sig has and the smith and wesson does not? And why wouldent all manafactures use the system sig has? It just seems to make more sense.
Sigs dont need to be cocked; trigger is always hot.

Most likely, your bud's S&W is a striker fired gun, like a Glock.
If it has a hammer, it should work just like your SIG.
Most striker fired guns have to have the slide cycled to re-set the trigger so it can cock the striker.

As did the 1st. Generation S&W Model 39/59.
As did the 5946 in question.
It will not work without a magazine in it.
The Ruger LCP has an internal hammer, but.
The slide has to be cycled to re-set it, which happens automatically when you shoot it.
But not while setting on the couch playing with it.

Sigs are only 'hot' once you chamber a round... once chambered, i decock it so it becomes a double action.. just like a double action revolver.. exactly the same.. once fired (or if you dont decock it after chambering a round), it is single action.. dont have it in single action mode and carry it unless you dont value your femeral artery!
Now that you mentioned the S&W is a DAO model there could be another reason why it won't fire. Despite what S&W says these models are actually partially-cocked like a Glock. They cannot be fired unless the slide is pulled back to partially cock the hammer. No second strike capability like on a true DAO.

A lot of pistol makers have designed their "DAO" pistols to actually be at around "half cock" instead of hammer / striker fully forward. Kind of a hybrid between single action and DA/SA. It lets them get away with a much lighter trigger. Most polymer striker fired guns do this. Several hammer fired guns do (kel tec P32, Ruger LC9). To my knowledge, the manufacturers don't tell you just how close to being fully cocked their pistol is. I have heard the S&W M&P is near fully cocked, but not sure.

The M&P is fully cocked. The trigger simply cams the sear out of the way for the striker to go forward. The trigger action does not cause the striker to move rearward (to cock it) in an appreciable way. So I'm still confused why it has such a mediocre trigger.

I think the OP's question is a result of having no background or understanding of how firearms work.
There are as many different ways to make a firearm busta primer as there are ways to count dancing angels on a pin head.
It takes a dedicated study of firearms design to understand them all.
I've been studying them since I was wet behind the ears in 1950 something.
And just about the time I think I know how they all work??
They invent some other way to do the same thing!!
But sometimes not as well.

Both guns may be marketed as being DAO, but their actions are different.
If your buddy's S&W has a hammer, I'm betting that it is more of a snub hammer than a full spurred one or a flush one...that would be the M-5946
The third number "4" denotes that it does not have second strike capability. Racking the slide leaves the hammer at half-cock, which shortens the trigger stroke
While S&W did offer a version of the M-5906 which was DAO and had second strike capability, the 5946 was designed specifically not to offer it.
In the photo below, you can see how the slide was extended further to the rear to cover more of the hammer and how there is more slide behind the rear sight. The two lower guns are DAO withou second strike capability. The bottom gun has it's hammer half-cocked, the next one up is uncocked

[/resize]Even SIG offers two versions of their DAO pistols. They offer a version which is simply lacking the ability to remain cocked in SA and they offer the DAK version which offers a lighter and smoother initial trigger pull...but retains the second strike capability with a heavier trigger stroke.

Excellent explanation!!
I had forgot more then I knew about the later S&W metal frame autos.
Because I never owned or worked on one.
But again, it takes a detailed study of firearms, and a keen memory to understand why some autos have to have the slide racked and others don't.
Thanks for that detail and memory refreshment on the various S&W autos!
