Jerry Miculek's custom spring kit includes a new hammer spring and trigger return spring designed to significantly improve the trigger pull weight and feel on Smith & Wesson revolvers, enhancing overall performance and shooting experience.

What is a safe method for installing the trigger return spring during a revolver trigger job?

A safe and effective method demonstrated by Jerry Miculek is using a common ballpoint pen to compress the new trigger return spring before seating it into the rebound slide, preventing slippage and potential injury.

How do you adjust the trigger pull weight on a Smith & Wesson revolver after installing a spring kit?

Trigger pull weight is adjusted by turning the hammer spring strain screw. Jerry Miculek targets 7.5 lbs, measuring screw projection with calipers to ensure it doesn't interfere with grips while maintaining adequate spring tension.

What factors should be considered when fine-tuning trigger pull weight for reliability?

Fine-tuning involves balancing desired pull weight against primer ignition reliability. The hardness of primers used (e.g., Federal vs. Winchester) dictates the necessary hammer force; the strain screw may need adjustment or filing.
