Holster Design & Build

Each holster is vacuum-formed for a precise fit, CNC-trimmed, and folded in-house. Final testing is performed with the actual firearm to verify retention and function before shipping. The high sweat guard and slim taco-style profile make this an excellent choice for concealed carry.
