These days, gun grips are available in different materials such as hardwood, ivory, rubber or plastic. However, I believe that modern designed special textured rubber grips are the most preferable choice among the users. Since, such grips provide proper ventilation in extreme heat and moist environments, which is very effective while shooting. While choosing a gun grip, you must consider the proper size, comfort and quality of material used to make them. Recently when I was searching on the internet, I found some good information about varieties of gun grips at https://www.zfi-inc.com/en/blog blog section. I hope it could be of some help to you as well.
