I have a set of bill jordan grips by pachmeyer. They were built on bill jordans idea. They are huge as he had hands like baseball gloves. They are rounded black hard plastic and are for the N frame. I see they have a narrow slot cut on the bottom so you can see the serial number. They are real light grips. They are smooth with a slight thumb rest for a right hand. I dont know if pachmeyer still makes them or not. I bought them about 30 years ago and never used them. I am going to put them on a gun and try them out again. I belive at the time I bought them that I found them even too big for my hand and I have large hands. Come to think of it I dont remember even seeing another picture of one here all these years. I may put them on one of my smiths and get my wife to take a picture of it. I will post back later.
