    1911 ejector installation

    I'm not a professional gunsmith I am an old S&W revolver and pistol armorer and hobbyist. I like working on 1911 pistols for my own use and enjoyment.

    I have staked front sights, plunger tubes, fitted thumb and grip safeties fitted barrel bushing, triggers, hammers and sears, but the one project that causes me to sweat bullets is installing an ejector. Fortunately it doesn't come up often, as an example, I converted a .38 Super to 9mm and needed to do it.

    Even removing the ejector is a concern. Some have little cut outs that you might use to pry up the ejector but the thought of breaking off a post freaks me out. After driving out the cross pin, I have mounted it in a padded vise and slowly wiggled it free from the frame.

    The two times I have done ejector installs I have dressed the part, installed it in the frame and then marked it with a punch, removed it and used a file to cut a pin size hole in the post.

    I saw a video online where a smith takes a 1/16 left hand twist drill and uses the cross pin hole as a guide to drill the ejector post:



    Has anyone here tried that and not messed up the frame? Seems much faster than fitting it by hand. Just a beginner seeking knowledge.

    I would not do it that way.
    If an aluminum frame, the steel pin is harder and will deflect the drill bit off the pin and into the frame.
    If a steel frame, this could also happen depending on the frame hardness.
    I would mark the spot, then remove the ejector and use a jeweler's round file to make the pin groove.
