First up a picture of the slide and frame together showing a good look at the guts even the mag catch. S&W don't recommend grease, and don't recommend any lube on the sear, that was my call.
Next up is a pic of the steel chassis molded into the rame. As far as I can tell, without taking it to pieces, both the trigger block and sear block are pinned into the frame through the chassis.
Next up is the striker with slide end cap. The striker has the striker spring, cups, and spacer still attached. The ungreased leg of the L at the back is what I believe engages the firing pin block.
A fuzzy shot showing the channel liner in the striker channel. It's the best I could get, and should convey the idea. The striker cups move along this
A shot of the sear block with sear deactivation lever lowered (sear deactivated).
A shot of the sear block with the sear deactivation lever raised (sear active). You will also notice a notch next to the sear deactivation lever. This is where the magazine disconnect would live if this gun had one.
Overhead shot of all the trigger bits in the frame with the trigger slack.
Overhead shot of all the trigger bits in the frame with the trigger pulled. Notice the little felt doohickey in the trigger spring.
Overhead shot of the trigger block with the trigger slack.
Overhead shot of the trigger block with the trigger pulled.
Overhead shot of the sear block with the trigger slack. (camera just did NOT want to focus on the rear of the sear block, so it's slightly blurry)
