So this all makes sense, and I have a question to further complicate matters:
I have two what appear to be gen 3 DB380s. Identical except for color, and the TRIGGER. One does not engage the striker until late in the overall trigger pull where it hits a break wall and then fires, and the other engages immediately and is heavy all the way back to break, with no wall. Upon disassembly, the trigger control group on the slide is different. You can see the two tabs are different on one vs the other. Is this known? I don't like that they're different. I'd like the two to be replicas, so they feel identical.
