It surprises me how many paintballers dance around one of the most elementary ideas of the sport of paintball… ripping paint! Now, I am in no way saying that your paintball skills solely rely on how many paintballs your shoot per second, but certainly you would agree with me that it has some importance. For example: You’re playing in a tournament, you and only one opponent is left in the game. You have the most accurate gun ever made, but you shoot 3 balls per second (BPS). Your opponent however, has his pimpin’ Smart Parts Ion and able to shoot 20 BPS. There is a small chance you would win, but the Ion player is much more likely. It’s just logical. Paintball isn’t just about accuracy, but logic. You must be able to lay down a line of paint at 15-20 BPS in order to provide coverage for your teammates. Point made.
That said, I have humbled myself enough to give a short and simple tutorial on how to increase the rate of your firing speed.
Get a rubber band, preferably two.
Locate a hand and fingers you’d like to strengthen. Preferably your own and attached to a body.
Proceed to wrap the rubber band(s) around your pointer and middle finger like so…
This part is optional, but highly recommended. Wrap the rubber band(s) again around your fingers to create more tension, and in turn strengthen your fingers in a more timely manner. 
This is the exercise. What you’re going to do is simply pretend you’re ripping on your favorite paintball gun. Proceed to lift one finger up at a time, alternating up and down, just as you would when walking your gun. Try varying the speed of how you’re doing this. Try going in slow motion, to “rip” the finger muscles in order for them to rebuild stronger than before. Now try going really fast. 
Do this every day for at least 5 minutes. Every week, see how faster you’ve become by using this trigger pull game as a way of testing your trigger pull BPS.
Force be with you.
