What is a 'good' trigger pull?

[SIGP2101]

Just by polishing areas indicated in red to a mirror shine (without changing geometry) Luger trigger action can be improved significantly. (DO NOT USE DREMEL FOR THIS)

Second part would be to install travel adjustment screws. This can be done on trigger itself or sear bar. There are multiple locations for this.

Third step in improving Luger trigger feel is to eliminate wobble completely from the plunger. Maybe required to built entire new and longer plunger. Longer means it will have to be seated deeper in new drilled hole.

Anyone can accomplish first step and immediately benefit greatly improved trigger.
