Hey Neil, I lucked out and came to the GTA when the GRT-III was introduced, and I went every where looking for a better Gamo trigger, well as you might guess, I bought the GRT-III, and it was better than I could have hoped ! Now to Rich, I have read that they are O.K. if epoxied to the trigger, but when they become loose, I have read that they can very erratic, some times O.K., sometimes bad to

I would put in a GRT-III, and never have to worry about it. After about three years, it has been consistent and true, now I have ventured into tuning it, and with Bob's excellent directions, have made my Great trigger into a Match- like trigger, and I have room to work on her yet !!! A little at a time. Personally, I wouldn't want that trigger insert in my gun, to may people have had problems, and I like to know what is going to happen when I go to shoot my bb gun ! ....Bill
