What some the best shooters in the world say about Progrip: 

Jerry Barnhart: "I've finally found a product, conveniently packaged, that works better than rosin or chalk." (USPSA Open Nationals and Limited Nationals Champion) 

Todd Jarrett: "Pro Grip is the best product for action shooting, a must product for every shooters bag. The perfect grip." (1997 USPSA Open & Limited Nationals and IPSC World Champion) 

Saul Kirsch: "The only down side to Pro-grip is that once you experience the advantage it offers your grip and gun control you simply cannot shoot without. This product will do more to improve your gun control and recovery time than any other!" (Silver Medallist European championships).
