I have a question about removing the mainspring, Is it necessary to bring the hammer to full cock before removal of mainspring as i read online and a book that i have. I did follow these instructions on one of my locks and it worked fine but i noticed after removal of the sear screw it seemed to have been bent a bit, i am not sure if the sear screw is suppose to be that way as i am not familiar with this screw. Would it be better to compress the mainspring while the hammer is relaxed forward so there is no pressure on the screws? anyone that can help i will appreciate alot. thank you.
