Precision Construction & Fit
Each holster is vacuum-formed using a precision-machined mold created from a CAD model of the actual firearm. All forming, trimming, and finishing is completed in-house.
Final fit and function testing is performed using the actual pistol to ensure proper retention, smooth draw, and reliable performance.
Retention is fully adjustable, allowing you to fine-tune draw resistance to your personal preference.
