DAA Flex / Flex Air Holster Insert Block

DAA Flex Insert Block Assembly – Adjustable Insert for Double-Alpha Flex Holster

The DAA Flex Insert Block Assembly is the core component of the revolutionary Double-Alpha Flex Holster system, delivering unmatched adjustability, secure retention, and compatibility with a wide range of competition pistols. Designed specifically for IPSC, USPSA, and practical shooting competitors, this innovative insert block allows shooters to fine-tune holster fitment for maximum performance and reliability.

Featuring the patented Flex Insert design, the system enables users to precisely adjust retention and fit using interchangeable side spacers, ultra-thin shims, adjustable slide-lock teeth, and an optional front spacer. This advanced configuration accommodates manufacturing tolerances between pistols, ensuring a secure and consistent fit that traditional fixed insert systems cannot achieve.

The Flex Insert Block Assembly incorporates an aluminum slide-lock mechanism with adjustable retention teeth and magnetic engagement technology, providing smooth and reliable operation during competition. The redesigned stainless-steel safety lever is wider, flatter, and positioned for easier access, allowing fast and intuitive activation when needed.

Thanks to the advanced injection-molded construction and rail-mounted magnetic support wedge, the slide-lock mechanism operates with enhanced stability and consistency, helping shooters maintain confidence and speed on every draw.
