Fix, did you replace the plastic washers at the hinge, or change out the pin with a better design? I plan to get the GRT trigger for mine as well. My quest trigger is tolerable now, but it took a lot of pellets to get it there. I actually think that the B-18 platform in these Crosmans make for a smoother to shoot gun than the B-20. As mentioned, I have the RWS 320, and it's faster, and locks up better, but it's buzzy. It's getting a JM tune kit put in when I get the time, the kit got here only yesterday.
