The ratchet mechanisms used in my works. I especially use them in the P200 series.
Currently, I have developed six ways to drive the "slide bolt."

A mechanism in which an independent ratchet pawl drives the slide bolt rack gear.
Used in the following models.

The ratchet pawl is integrated with the trigger.
With a pivot at the trigger tip, the trigger acts as a large ratchet pawl to drive the slide bolt rack gear.
Used in the following models.

The ratchet pawl is integrated with the trigger.
A linkage in the grip allows the trigger to act as a large ratchet pawl, driving the slide bolt rack gear.
Used in the following model.

The ratchet pawl is integrated with the trigger.
By providing guides above and below the trigger with a front-to-back offset, the trigger acts as a large ratchet pawl to drive the slide bolt rack gear.
Used in the following models.

A built-in ratchet pawl in the trigger is pushed upward by the finger pad to drive the slide bolt rack gear.
Used in the following model.

A mechanism without a rack gear, in which a rod is driven via a lever mechanism inside the trigger.
Used in the following model.
