The last thing you need is the nuisance of hurt or bleeding fingers during a competition, not to mention broken finger nails. The Super Thumb Jr. is simply a means of holding the often difficult button on the side while loading your magazine during matches. It holds the button down comfortably while you’re enjoying your sport, either at a match or at practice. In this package, you get two Super Thumb Jrs., specifically designed for a variety of target pistols. The red model fits, Browning, Colt, High Standard, Ruger and S&W 22A/S types of magazines. The blue model fits Smith & Wesson Mod.41 and Walther GSP type magazines.
