I'm new to this, folks, so be patient. I purchased from Gamo USA a new CFX, and on the same day a new GRT III upgrade (9-9-09). Most everything I see on this site says the GRT III is the thing to have. After reviewing all the installation info (ala CDT, Joe Meyers, Chuck Adams, et. al.) I have decided I have a new species of trigger because it doesn't look anything like the ones shown in various instructions. The new blade is a polymer, not stamped metal. I will try to include 2 images of the new assembly if I can figure how to do that. Question is: will the GRT III work with this new configuration, or do I have to renegotiate with CDT?
