The "recoil" springs in these are from the actual powder-burning pistol and therefore WAY to strong for the air gun venue. As the pistol does not have "simulated recoil" the strong spring is NOT necessary and totally not practical. Cut off a couple of coils as has been suggested and if for some inane reason that does not work for you, then replace the spring with a readily available original. You will NOT detract from the value by shortening the spring-it will just make the experience more reasonable. The Crosman route is not a better way to go!
