Tom,
I know that you will enjoy the Shock-Wave that you bought for your son.
Did you really buy it for your son or plan on "holding it" for him for a "while"
Take a look at the Thunder Ranch review and use of the Shock-Wave.
Clint Smith does an excellent job in demonstrating the correct technique of shooting it.
Remember to have your hand in the fore arm strap. It is there for a good reason.
Wayne
