I have a question that I hope some people could clear up for me. What does breaking a pistol barrel in do? How to do it properly? And why? All my guns I own I just f strip clean and shoot about 150-200 rounds through em at range the first day. Go home and clean it then put it in safe. Just to make sure it cycles good. Am I doing something wrong? I heard some say shoot/clean, shoot 2 rounds/clean, shoot 3 rounds/clean, and etc. until you reach up to 6 or 7 rounds. Is that REALLY necessary?? And does it REALLY help with grouping?? Thanks in advance people.
