There are a few things you can do to customize your paintball gun grips. One option is to buy a new set of grips and swap them out yourself. You can also buy grip tape and apply it to the existing grips. Or, if you’re feeling crafty, you can make your custom grip wraps out of textiles or other materials. whichever method you choose, be sure to test the grip on your gun before playing to make sure it feels comfortable and provides the right level of grip.
