Bianchi Single Mag Pouch Black Size 21 Snap Hidden 40mm. The Single Pouch is reinforced and designed to resist anything that tries to encroach on the magazine envelope. The strong Snap attachment reliably holds your magazine secure yet allows for easy withdrawal when the magazine is low or the light duty firearm is off. Our classic Choc-Key pattern and standard single scan-line design is simple yet affective. The Choc-Key offers exceptional grip when wet or dry the textured surface catches the light source and holds the magazine fast as lightning strikes. Many shooters like the Choc-Kit as well for the convenience of which they can be attached anywhere using the double hold-down feature.
