Action Enhancement Kit for SDVE

This Action Enhancement Kit directly addresses the known shortcomings of the S&W SDVE (and SD) series factory trigger: a heavy, gritty pull with excessive pre-travel and a vague reset. By replacing the sear, trigger spring, and related components, this kit reduces pull weight by approximately 2 lbs, cuts pre-travel by 20%, and reduces over-travel by 10%. The result is a smoother uptake, a shorter, more defined reset, and a trigger that remains suitable for duty, carry, or personal defense while improving practical accuracy and split times.

Key Features

• Pull Weight Reduction: Approximately 2 lbs lighter than factory (actual pull weight depends on individual pistol and installation).
• Reduced Pre-Travel: 20% less slack before the sear breaks, improving first-shot consistency.
• Reduced Over-Travel: 10% less rearward movement after the break, aiding follow-up shot control.
• Improved Reset: Shorter, more tactile reset distance for faster follow-ups.
• Centered Pivoting Safety: Maintains factory safety values; no compromise on drop safety or sear engagement.
• Direct Drop-In: No fitting or gunsmithing required. Includes replacement sear, trigger spring, and related components.

Frequently Asked Questions

Will this trigger work in a Sigma series pistol?

No. This kit is designed exclusively for the SDVE and SD series. Sigma frames use a different sear housing and trigger geometry.

Does this kit include a new trigger shoe or trigger bar?

No. The kit replaces the sear, trigger return spring, and sear spring only. The factory trigger shoe and bar are reused. The improvement comes from the sear geometry and spring rates.

Is this legal for USPSA Production division?

Yes, as long as the pistol remains in the factory configuration (no external modifications) and the trigger pull weight meets the minimum 2 lbs requirement. This kit does not alter the external appearance or safety mechanism.
