Finger Band Extensions
When it comes to grip training, the extensors are the most neglected variable. The body will limit absolute strength potential if the antagonist is weak in order to protect the joint. Therefore, train the extensors of the hand/wrist. Try this: Get a fat rubber band and place your fingers inside it. Spread your fingers as wide as possible without the rubber band rolling down your fingertips and then close them. This is also an excellent exercise for anyone with wrist or carpal tunnel problems!

Great point. I’m a guitar player and spend about 2-3 hours a day “training” my forearms and grip (practicing. I’m working towards a Bachelor of music). The same thing holds true for guitar as it does here: the extensors are the weakest link of the forearm. The better and more muscular they get the faster and stronger your fingers and grip are.
The rubber band idea is a good one. Try this as well: make a fist then “flick” your fingers outward from pinky to index on both hands. the key is to feel the fingers resist against the palm of the hand then snap out. Works wonders for a guitar technique called rasgueado, but also really works the extensors of the forearm. Just some thoughts.
