Frequently Asked Questions

What is the "Yoda G Mod" for Smith & Wesson Airweight revolvers?

The "Yoda G Mod" is a gunsmithing technique to improve the trigger pull of S&W Airweight revolvers like the 638. It involves careful disassembly, stoning internal parts to reduce friction, and installing a reduced-power spring kit for a smoother, lighter double-action pull.

How do you safely remove the side plate on an S&W Airweight?

Master Gunsmith Terry Gardner recommends 'bumping' the frame rather than prying the side plate off. This technique helps preserve the tight tolerances of the aluminum frame and prevents damage during disassembly.

What parts are used in the "Yoda G Mod" trigger job?

The "Yoda G Mod" typically uses a Wilson Combat spring kit, specifically a reduced-power rebound spring (like 13lb or 14lb for J-frames), and fine Arkansas stones for polishing internal contact surfaces.

Why is it dangerous to cut factory S&W revolver springs?

Cutting factory springs can significantly reduce the hammer strike energy, potentially leading to light primer strikes and misfires. It compromises the firearm's reliability and safety, making engineered reduced-power spring kits a much safer alternative.
