Custom FCU Refinement & Non-Standard Requests (SIG P320 / P365)
Smoother + Shorter Press → Less Muzzle Movement → Greater Accuracy
This listing is for requests that fall outside the standard SIG P320 and P365 packages available at our shop: pewcentric.com/precisionfcu
Overview
Not every build fits a predefined path.
This listing is designed for shooters with specific goals, unique setups, or requirements that require a more tailored approach.
All custom work follows the same core philosophy: improving accuracy by minimizing unnecessary movement in the system.
When to Use This Listing
Use this listing if your request involves:
Non-standard configurations or components
Specific performance goals beyond standard offerings
Multi-platform or multi-FCU coordination
Adjustments based on prior work or existing modifications
Questions about feasibility before committing to a standard service
If your needs are already covered by a standard P320 or P365 listing, that is the recommended path.
