I tried the rubber grips from 3 manufacturers over my time carrying - 50+ years. I have found Uncle Mikes rubber grips to be the best. There is another company that makes them for big gun company's like Colt but I do not recall their name. They came on Dick Specials. Pachmeyers are IMO the stickiest, bulkiest and will rust your gun if left on. My suggestion is if one is to use Pachmeyer grips for a shooting session, matches or when on a hunt, take them off when done. As far as the worth of the grips in your picture is concerned...... not that much. New I believe they sell for under $50 bucks. Used - probably less than half.
