Trigger Issue - mini clicks

[mrstimpson38]

I recently picked up a new CM9 from a local shop and put 100 rounds through it. It performed well, but the trigger had an issue before and after I fired it.

When pulled, it feels like there are mini ticks, or clicks as I pull it back. Very, very light break points that are both tactile and audible. Upon breaking it apart, it sounds like it is coming from the trigger spring, but I can't be certain.

I've tried lubing it, constantly pulling it, shooting it, cleaning it, and It's still there. I'd like to avoid returning it or sending it to the shop, so I'd like to know from you guys what this issue sounds like, if it's a common occurrence, and how I can fix this issue.

Thanks guys.

I just got the same thing in a brand new CW9. Trigger bar or spring, can't really tell which. It functions fine, but the trigger pull should be smooth as glass and not creaky.

It's the Trigger Bar and Trigger Bar Spring sliding across each other. To verify, remove the slide and watch these parts as you pull the trigger. If it's like my CW9, you'll see the spring jerk as the bar moves.
