I tried searching for previous post on this but couldn't find anything. I would like to know if anyone has installed a shim kit for there GP100 and what size did you use for the hammer and what size for the trigger. I am fixing to order a kit and a wolf spring kit for my GP100 and would like some feedback. I definitely need one for my hammer as it has little side to side play and sits slightly closer to the frame on the left side than the right. Thanks for the feedback.
