springer shot cycles are harsh, Gamo being one of the worst. Most people that stick with Gamo disassemble and tune the harshness out of them. They have one of the loosest spring to guide clearances resulting is what we call "TWANG!".
Just a heads up. Enjoy the hobby, it's great fun, has plenty of good folks in it and offers more shooting opportunities for frustrated powder burners who can't get to the range or field as often as we'ld like.
