The BLACKHAWK TecGrip FormLok Size 01 is a thermoformable inside-the-waistband holster engineered to be molded to the user’s handgun for passive retention. The laminate construction combines a tacky exterior that adheres to body and fabric, closed-cell foam for comfort, and an internal Memory-Lok core that softens with heat for custom forming. The holster is ambidextrous, offers a low-profile shirt guard, and features a low-cut sight channel optimized for use with mounted RDS optics. A T-handle molding tool and a heavy-mil dunk bag are included to guide the molding process.
