Bigun, for a start, either bend the middle leaf of the sear spring forward or replace the spring. As a retired military armorer, I have seen this which we described as "hammer follows slide forward" type malfunction. It may be caused also by the slide binding when firing rapidly due to heat which prevent incomplete retraction of the slide but this usually leads to incomplete ejection. A heavy recoil spring will cause the same symptom. If this is not a "blueprint" slabside, you may have a defective disconnector. If all else fails, take it up to George Stringer, he is just over the border in "Kaintuck". He's on every gun link, including this one. He can almost make a "ferin" "45" like a government model.
