An offset magazine release button includes a body portion and a generally stairstep-shaped end portion. The body portion may be inserted into a magazine release opening of a firearm. The stairstep-shaped end portion may include an indention portion providing or creating a floor or floor portion and a narrow stairstep riser. The floor, when part of the assembled firearm, is generally flush with the firearm's gripping surface to create an augmented gripping surface that may allow the operator to have a higher grip to help control recoil. The end portion also includes an offset contacting pad. The floor transitions to the riser, which then transitions to the pad. The pad has a generally perpendicular ledge or surface extending toward an actuating thumb position of the operator's grip. The pad surface may be textured to provide for better contact with the operator's thumb when depressing the button to release a magazine.
