I have a CM9. I have had it for almost a month. I have shot the recommended break in and all have run flawless. I guess I would say I have 300 ish through it now. I notice the other day that the trigger would not reset. I was shooting pmc and figured it may be a ammo issue or cleaning issue. It fired fine the first 50 of the day and I thought maybe it didnt like being dirty. I came home cleaned it and took it to shoot today. I find its the trigger wont reset and has to be pulled to reset manually. I tried two different ammo before I realized that wasnt the issue. I am wondering has anyone else had this issue or have any ideas. I love this gun the DAO trigger is my favorite part but I dont feel safe with a single shot.
