The Kydex Holster NX300 OS Alpha is a precision-moulded open-slide holster engineered for light-bearing and modified pistols. Built from rigid Kydex, it provides consistent retention and repeatable draws while accommodating open-slide designs and barrel attachments. The profile is cut to accept EU-series pistols, 5.1" Hi-Capa models and 1911/MEU platforms — and the mould allows compatibility with other similar form-factor replicas. The open-slide geometry makes this holster especially suited to pistols fitted with suppressors, tracer units, or extended barrels, ensuring no interference with slide or barrel components. Adjustable retention hardware and multiple belt-mounting orientations let users tune draw tension and carry angle to preference, making the OS Alpha a practical choice for skirmish, competition, and display use.
