Sometimes when I put the P-10 C slide back on the frame something jams and the pistol simply won't go together. Usually the barrel and guide rod are sticking out. Worse, the slide can't come off the frame. I pull the trigger, wiggle the barrel, whatever. It's very difficult to solve. I'm left with about an inch of slide hanging off the rear of the frame.
A couple of nights ago I decided to remove the striker to see if the slide would release. I reached in with a punch and took pressure off the slide cover. I slid the cover off and -- SPROING -- the striker flew eight feet across the room. I picked up the striker. At least the slide now came off the frame easily.
I reassembled the striker into the slide and reassembled the pistol. It seemed to function normally.
Next morning my wife was vacuuming and found a little chrome pin. I knew the striker had come apart.
The pin was the Automatic safety pin (3g on the parts diagram). Fearing the worst, I looked around and found the tiny Automatic Safety (part 3d). I then watched the video below and discovered the really tiny the Automatic Safety Spring -- part 3f -- was missing. I ran a large magnet around on the floor where I thought the spring might have gone and -- amazingly -- found the spring.
In order to reassemble the three parts of the Automatic Safety I consulted the video below. It was very helpful.
I don't need nor recommend the trigger polishing job. But the striker reassembly section that starts at 16:30 really helped.
Moral of the story: be aware the striker has parts that can easily depart and are a challenge to 1) find and 2) reassemble. Fortunately I have tile floors and found all three parts, eventually.
