At that level of detail, your best bet is to find a good gunsmith.
Needs to be look at by a gunsmith
To disassemble a Bryco Jennings Nine with the sear in backwards, first ensure the firearm is unloaded and the magazine is removed. Begin by removing the slide from the frame by pulling back the slide slightly and disengaging the slide stop. Next, remove the recoil spring and barrel from the slide. If the sear is installed backwards, you may need to carefully remove it by accessing the trigger assembly and reversing its orientation to ensure proper function. Always consult a detailed manual for guidance specific to your firearm model.
Springfield

According to Sears Archives, that model was produced from 1961-1971.
The word "sear" can mean to burn or scorch the surface of something, especially food. It can also refer to making a permanent impression or mark on someone's mind.
It depends on which brand and model, but in general, it is inside the slide near the rear of the gun.
50-250 USD or so
