Can anyone who owns a BP9CC help me out here?
We picked one up last Feb. And it has been a good shooter until a few weeks ago. It started having an issue with not resetting reliably.
I have figured out what is happening but I am not sure why.
There is a spring, the "sear retainer spring" that keeps pressure on the the "sear retainer" or the mag disconnect cam. You can see the spring in the picture.
What isn't very clear in the pic is that there is a small hole adjacent to the pin that the spring is wrapped around. There does not appear to be anything to capture the stationary leg of the spring, but if there was a pin/post/retainer of some kind in this hole it would be in the perfect place to do the job. The loose leg that can be seen in the pic is actually about 180 degrees CCW from it's home position which is against a shelf on the sear retainer. The spring looks to be intact as referenced from a picture of the replacement parts page on bersa.com. Unfortunately, I have not been able to find a parts blow up diagram to see if there is a missing piece.
Has anyone taken their BP9CC down this far that could verify if I am missing anything?

I have posts at bersachat and the bersa.co forum
There is very little activity at either though someone pointed out the key grease points on the sub frame.
I actually just got off of the phone with a Gunsmith at Bersa's service center in Baton Rouge, LA. He was very helpful and did verify that there is a roll pin missing from the hole in the sub frame. He said that he's seen 4 or 5 with this issue.
It seems to me to be a weak design(the roll pin), a purpose specific flanged pin would have zero chance of ever working free and falling out. I asked if he would recommend peening the roll pin a bit to help keep it in place more securely. He said that is what he did for the few that he repaired.
So now I just need to pick up a 2mm roll pin.
I could not find a 2mm roll pin but a 5/64" pin was a perfectly tight fit. The Bersa is up and running again.
So if anyone else experiences this issue, a 5/64"x 1/4" roll pin will do the job nicely. The sear assemble is very simple to dismantle and reassemble with the aid of a small nail as a slave pin to help align the sear and spring.
