Glock 20 & 21 Holsters

Secure your heavy-hitting large-frame platform with our premium collection of custom-molded Glock 20 and Glock 21 holsters. Handcrafted in the USA by Muddy River Tactical, these holsters are precision-engineered to perfectly match the massive slide dimensions, standard accessory rails, and robust frame geometries shared across Glock’s flagship 10mm and .45 ACP handguns.Because these powerhouse calibers utilize a significantly wider slide and heavier chassis than standard 9mm Glock models, an exact factory-spec mold is necessary to guarantee absolute firearm security, zero rattle, and total trigger safety.
