of Rich's inserts. Both work very well and are vastly better than the Gamo factory trigger. Although the new version is called the short stroke, I personally didn't really notice much difference in the length of the trigger stroke. Also, I did not bend the spring as he recommends because I had been planning on getting the GTX-G2 when it came out. When I got the GTX-G2 and installed it there was a definite difference. The second stage with the GTX-G2 is much more pronounced making it easier to tell where you are in the trigger pull and hold there. It is also a very repeatable trigger pull. As far as I'm concerned the cost of the GTX-G2 was money well spent. You can't go wrong whichever way you choose, both are far better than the factory trigger. Here is a link to a review I did on the GTX-G2:

Edit: By the way, if you have been considering the other gold trigger you should read what Craig had to do to end up getting it to work like it should. Here's a link to that:
