So I got all new parts (below) to try to fix an issue with my EDC Gen4 G19. Monday I am going to hit the range and see what the outcome is. Meanwhile I'll be dry firing.
30274 ejector in a new trigger housing.
Recoil spring, you can see new spring (bottom) is less compressed than the old spring (top).
Extractor depressor spring, silver is new.
Slide lock lever.
Firing pin plunger and spring.
Firing pin spring (new on bottom).
Extractor, Apex (old) vs new (left)
