I put together a CA 380 from a bunch of part guns, it works ok. Had 8 or 9 hiccups (probably the magazine or maybe the recoil spring, not sure yet). With that said, the trigger is pretty rough (and that is being generous--LOL). Might be a losing cause, is there anything that can be done to smooth out the trigger? I seem to recall watching a video of a guy smoothing out parts of the trigger assembly in a SNS (don't remember what kind though). Thank you in advance.
