Is that the "newest" trigger design?
My P07 (DUTY pistol) has a trigger with a more pronounced curve to it. More like the CZ 75s. My P09 has a sort of three angled trigger. Straight in the middle, but slightly curved at the top and bottom.
If you were happy about the way that one felt on your finger, just replace it with the same version.
And I agree, never saw that type of breakage before. Sooner or later, you see some strange things.
