for the cp triggers on the DM7/8, I've had to sand down where it's making contact on the upper part of the trigger, should be right above the bearing where it's making contact. Had the same issue on both my wife's and my own personal markers. First time I ran into the issue was in the DM7... see if you can't find where it's snagging (like I said, it should be right by the bearing) and see if it's feasable for you to sand it down to make it work. I've managed to do so on mine, since the rake trigger from cp is my favorite, and I refuse to go elsewhere. Let me know what you find please, if you can't see the problem there, let me know and I'll take mine apart to verify what I had to do.
