My pins look just like the one in the Keith Brown photo, the tip is shaved off to an approx 1/16" blunt end - that's how they came.
When my canopy latch pulls the pins in, the end of the pins are recessed behind the plate about 0.25 mm.
The only thought I have is that your C-01430 Latch Bellcranks are installed upsid'zy down.
Another thought today after looking again > More probable, the adjustment of the rod end bushings each end of the torque tube between the canopy latch handle and the bell crank that operates the pins.
