Precision Fit and Retention
Each holster is vacuum-formed using a CAD-modeled, precision-machined mold of the firearm with the light attached. Every holster is formed, trimmed, and hand-finished in-house. Final testing with the actual Glock pistol and Streamlight light ensures proper retention, which can be adjusted to your personal preference.
