The Black Widow belt slide holster is worn on the hip and offers an ultra hi-ride carry and a thumb snap closure. The dual belt slots provide stability, and its open muzzle design offers pistols of the same model with different barrel lengths. Its compact profile and widely spaced belt slots allow the pistol to ride close to the body for both comfort and concealability. This model is compatible with Glock 20, 21, 29, 30, 37.
