Hands come in different sizes.
Some are large, some medium, some small. Then some are gigantic, equal to a # 8 cast iron skillet or that's what I thought of when I shook hands with Bill Jordan.
Parts of the hand vary in size, long fingers, short ones and on & on.
Revolver grips vary in size, material, design and features.
One of the most important things in the equation of becoming a shooter.
Selecting grips for your revolver is very personal. Folks can recommend brands, styles and materials to you but you have to go through trial and error to find what works for you.
It may cost a dollar or two before you find the right one for you.
It's is why there is such a wide variety of makers & manufacturers
in the grip business. Folks & Shooters are constantly seeking the perfect grips.
Good luck in seeking what works best for you.
