Abstract: An expandable modular rack for storing at least one pistol of any width and/or at least one similarly configured item in its/their normal upright position. The expandable modular rack includes at least one first member, at least one second member, and at least one third member. The at least one first member, the at least one second member, and the at least one third member are interchangeably attached to each other, side-by-side, so as to form at least one bay. Each bay is defined by a vertical portion and a horizontal portion. The vertical portion of each bay supports the barrel of an associated pistol or an associated similarly configured item, the horizontal portion of each bay supports the heel of the grip of the associated pistol or the associated similarly configured item, and each bay is of varying width, thereby allowing each bay to store the associated pistol or the associated similarly configured item of any width in its normal upright position.

Abstract: An aiming improvement device for attaching to glasses having lenses and arms and worn by a shooter having a dominant eye and a non-dominant eye and for at least maximizing depth of field of the shooter and preserving depth perception and binocular vision of the shooter. The device includes an opaque aperture-adjusting assembly, a translucent shade, and attaching apparatus. The opaque aperture-adjusting assembly selectively overlies the lens communicating with the dominant eye to maximize the depth of field of the shooter. The translucent shade selectively overlies the lens communicating with the non-dominant eye to preserve the depth perception and the binocular vision of the shooter.
