I have owned a Gamo Hunter 880 for close to 10 years. It was my first spring gun. Although powerful and accurate, it just was not that much fun to shoot. It hasn't seen much use in the last few years.
Finally, after much procrastination, I installed a new trigger. Well, the accuracy and feel are so much better, that it is like I just got a new gun.
Now I can hardly put it down, shooting it everyday.
Can't believe how much the accuracy is improved.
Just do it.
I just got a Shadow, and I love shooting it. However, I have noticed that if I am not COMPLETELY still through my shot, I have a tendency to push my gun to the left right at the end of the shot, due to the stiff trigger action. I am seriously considering a new trigger, probably the GTX. What did you install, where did you get it, and why do you recommend it so much?
