My wife had to have an LC9, and if momma ain't happy ain't nobody happy, so now she has one :)

Ruger says it's DAO, but upon inspection I notice a few things:

First, the trigger is totally dead unless you rack the slide. No click click click like on a DAO gun, and no decocker.

I pulled it apart and figured out that racking the slide pulls the hammer back fully, but lets it fall back to a half cock position.

Once half-cocked the trigger pulls the hammer back and then lets it fall.

Looks to me like somebody could make a fortune selling kits to make the gun cock to the full position and stay there and make the trigger just drop the hammer.

I think of these as 1.5 action. It is not single, because the trigger pull does complete the cocking of the hammer and it is not double as you noticed because the trigger will not recock the hammer from the fired position.

Of course, this is the same as most compact "pocket" guns and striker fired pistols.

Don't know about making a kit like that. You'd effectively be making it single action but a big selling point on these little CCW pistols is "DAO" action.

As I think about it,I think a "real" Double Action
is a gun that can be shot by pulling the trigger
which cocks the hammer back as the trigger is
pulled like the LC9,OR the hammer can be cocked back
manually.Then shot.So I guess this is not a true Double action.

It's not DA or SA I believe. The hammer is at half-cock after racking the slide, just like the LCP. I might not be correct, but I think the PF9 is the same way.

I love everything about the gun but that trigger. I'm sure I'm not the only one.

single action guns fire from a fully cocked position, double action from a fully uncocked position we need a new term for these half-baked half-cocked single strikers

horrible double action. takes about ten minutes to pull it though the full stroke LOL

true double actions preform two actions during the trigger pull: cocking or retracting the hamme or striker, then releasing it.

While I'm not familiar with the Ruger, if Ruger says DAO, it is DAO. Glocks and the S&W M&P are DAO as well. The striker is partially cocked when the slide operates. Pulling the trigger does 2 things. First it finishes cocking the striker, then it releases the striker causing the gun to fire. Since it does 2 things it is double action. I assume the Ruger operates on a very similar system.

The XD is the only striker fired gun that has the striker fully cocked when the slide operates. Pulling the triger does only one thing, (single action). Almost all police departments require guns to be either double action, or double action only to be considered for purchase. This is the primary reason XD's are rarely seen in LE. I'd bet Ruger would not have made that mistake. They are targeting non- law enforcement folks for their sales, but would not make a gun that would not even be considered by most departments.

while they may call them the same, going from half-cock and going from un-cocked are two other things when i'm buying a self loader, especially in a bellygun. i want to know what that trigger is doing before my money comes out.

I disagree. I really like Ruger but just because their ad department calls it something doesn't make it so. Double action means that one can endlessly dry fire without having to do anything other than pull the trigger. Double action offers a second (or third or fourth) strike on a dud round (whether that is the best choice at the time is up to you).

In the case of the 1.5 action triggers above, the trigger only does two things IF you prep the hammer first... IF the hammer is at the half cock position, the trigger will finish cocking and release the hammer. OTOH, if the hammer is in the fired position, the trigger does nothing. That is NOT double action.

The duality SA, DA is no longer valid today. Human ingenuity has invented some different ways to strike the primer, hence a handgun may be DA, SA or anything else.

single action and double action are still valid. manufactures just need to let consumers know what they are buying. after all it's our money and we have a right know if we can get that second strike

^^true.

however, many firearms consumers don't know the difference anymore as there an many different types on the market now.

for example, the xd is single action, the m&p and glock are double action, but to many, they all seem to be the same striker fired type action :)
