Just replaced the blade in my trigger unit for my Gamo and now it doesn't seem to have any 1st/2nd stages. It is now extremely sensitive and when you touch it, it fires instantly. The same trigger unit with my standard Gamo trigger in, had 1st/2nd stages previously.
Is it just a case of adjusting the grub screws located on the underside of actual trigger?
