CZ Shadow 2 Half Cock in rapid fire or racked vigirously.

[EZ128]

About 10K rounds. Comp Hammer. Comp Disconnector. Original Sear. 10% less power sear spring. All were working perfectly but started to go half cock in rapid fire ( anything less than 0.50 split). I can simulate it by racking it vigorously.

See video here: https://youtube.com/shorts/ADA88UBZx_M?feature=share

When racked in a "normal " way  ( or in slow shooting), the hammer will not follow or go into half cock. Even when pushed hard, it will NOT fall or follow.

I guess this is either a timing issue? Would like to understand it before replacing the hammer/sear/spring etc.

Thanks!
