A tattoo gun improvement comprised of an adjustment means for the main spring of the tattoo gun that permits adjustment of the angle of the spring relative to the frame and therefore the spring tension against the needle depth adjuster. The means of adjustment facilitates quick and accurate tension setting on the spring while avoiding the need to bend the spring or alter the needle penetration setting adjustment. By avoiding bending the spring the spring life is extended as well as the precision that the spring tension may be adjusted. A precisely and properly adjusted spring can allow the tattoo gun to be used with less power that further can result in less unnecessary trauma to the skin.
