Notice that none of the springs are installed. This has no impact on illustrating what is going on but if they are in place it sure makes holding the camera and the pistol much more difficult if you are doing this all by yourself.
My finger for example replaces the mag safety spring in pressing the safety foot down. Other components have been placed in their proper position for illustrating what is going on. The only error is that the nose of the hammer strut is positioned a little too low. When the left side of the frame is installed, a floor, pictured later, fits under the strut and does not allow the nose to drop as low as it is in some pictures.
Disregard that sentence "also notice that the". What I meant to say is that the hammer is not far enough rearward for the sear to engage the cock notch but that isn't important as the sear is kept rotated out of the way if everything is working properly. The sear plays no part regarding release of the hammer in DA. Walther wouldn't have put those slanted pins in the side of the frame if it worked some other way. Caution, the tolerance and timing here are critical which means don't jump in there and start grinding on stuff. Polish.....yes, file and grind....no. Here is what is happening above in DA. The trigger bar is being moved rearward by the trigger. The trigger bar has engaged the hammer strut and begun to rotate the hammer rearward. Looking closely you can see this in the picture above and that the top part of the rear trigger bar legs are barely engaging the sear and have rotated it out of the way of the hammer. With the trigger bar properly positioned, the sear barely held out of the way, the rear shoulders of the trigger bar slide down the steel pins until the hammer strut slips off of the trigger bar allowing the hammer to fall. DA release....totally different from SA.
