I had a couple bad habits that I have sense stopped doing , but did for a long time . I used to drop a round in the chamber by hand and let the slide slam home. I also would rack the slide to lock-open then hit the slide release without a round in the chamber... loved that sound. Now I know better than doing either stupid thing, why the guys at the gun shops I purchased at never said a word about the care and feeding of a 1911 is still a mystery. What bad habits did you all lose ???This may be a good post to have new owners learn from so fess up.
