Double Alpha Flex Holster Locking Block

 This insert design allows each user to adjust and fine-tune his insert block to perfectly fit his particular pistol. Not only does this allow us to support almost all gun types with just two models of inserts (Type-A and Type-B), but it enable users to adjust for the small variances that are often introduced by the gun manufacturers, who don’t consider the external dimensions of the trigger guard to be critical. This has always been an issue for the Alpha-X inserts, and this problem is now solved with the new Flex insert design. 

 Now, using the adjustable slide-lock teeth, the selection of side spacers and Shims, and possibly the front spacer, each shooter can achieve a perfect fit to his or her pistol.

The Flex Insert Block Assembly features an aluminum slide-lock mounted with user adjustable slide-lock teeth. Magnetic engagement, as in the latest generation of Alpha-X inserts. The new stainless-steel safely level is wider and flatter than that found in the Alpha-X blocks, and is mounted on the right side of the block, the outside of the holster for all RH shooters. This makes it more accessible and easier to activate. 

 The new injection molding production process, and rail mounted magnetic support wedge, ensure the slide lock is more stable and moves more consistently than ever.
