Maybe this video is what you're looking for, and it does give you some ideas on the Striker Assembly.

I'm still having a bit of trouble in understanding how the "sear" drops down to release the striker when the trigger is pulled. There are some good animations showing the action of a Glock and I understand now why the striker end piece is tapered - it slides over the "sear" and engages it to be pulled back during the return of the slide.
I really can't see how the striker is released in those animations. I did come across one Glock article that shows an "Armorer Slide Plate" to check the engagement of the trigger bar (sear?) to the striker. That slide plate had the bottom section cut away so you could see part of the action.
I was able to use a flashlight and watch the striker action on my SD9 during a dry fire but just couldn't see what caused it to be released. Has to be very simple. I couldn't duplicate the "sear" action with the slide off.
Does S&W sell an Armorer Slide Plate for the SD series? Or, can anyone give me an explanation to what has to be my very dumb question?

What I have seen from looking at the sear. As the trigger is pulled the sear moves rearward and down away from the striker. If you have the gun apart and operate the trigger you will see this happening. Near the end of the sear travel rear ward it has pulled the striker back then a little more trigger pull moves the sear down and lets the striker go. Firing the cartridge. So when the pistol is loaded it is only at half cocked position. Pulling the trigger completes cocking as it were and releases the striker. This being the double action they speak of for this pistol. Hope this helps. These are only my observations.
Thanks,
I can see the sear rotating slightly as it moves back during trigger pull, but it's a tiny amount. In my CA version the sear seems to ride down a ramp which has too be held up by a lever that is lifted up by the magazine.
What I find interesting is that this very gradual downward movement must be very precise to fire the gun at the same trigger position every time.
[In a CA gun, the magazine has to be in the gun to connect the trigger bar to the sear assembly and at the same time lift up the ramp that the sear slides on. Maybe I should make a little video of that action on a CA version. Scott at Apex plans to make a second video using a CA gun, which is considerably more complex in the trigger bar/sear area than the standard version. I don't know the time frame for that project.]
