Sometimes the disconnect, "with other trigger parts" will be a little out of spec and will not tip forward enough to allow proper disconnect engagement . This was quite common with the early SGW Franken guns back in the 1980's. We would file the disconnect flat down just enough to acquire proper depth for engagement. I have also noticed shooting AR type pistols off a bench, "compared to a rifle using a proper shoulder mount" enhances bump firing, especially builds with light triggers.
