    Default Kimber 1911 9mm - work in progress

    Started a Stainless Kimber 9mm project for a customer. First on the list of things to do was add a Stainless KKM gunsmith fit ramped barrel.

    Below is the side by side of the old and new.


    First step was to measure the hood width and machine it to the proper width while still ensuring proper positioning of the barrel.

    Once the width is proper then the hood length is cut to fit. This process is more in depth because it has to do with a solid top lug lock up. is machined close and then fit by hand using files. I want a tight top lug lock up.


    I don't normally blacken the hood but this allowed me to take a pic and show what I'm doing. I put the barrel in and find the high spots and file them down until the barrel will lock into place properly.



    Hood and top lugs properly fit. Results was a solid lock up with .045" of engagement on the top lugs.

    I could have gone with the lower lug fitting or the bushing next. Went the route of the bushing. This was an oversized straight bushing. So once the ID of the slide and OD of the barrel was measured to the .001", I got to work on the lathe.

    A properly fit bushing requires a wrench to remove it as the fit is very tight. After this step was done I check for barrel spring and ensure there is none as that will create vertical stringing shots. If there is any it's addressed. None was present.

    Like everything the lower lugs were cut on machining equipment for a precision lockup. Accuracy and reliability are our goal and that can only be accomplished this way.

    After all measurements were take the lower lugs were cut and fit to the pin OD in the gun creating a solid lock up. Since this is a range gun and not a competition gun I went with a good lock up and not one that is overly tight.


    This is NOT the 9mm barrel, I forgot to take pics so I'm using these to show how this task is performed by me.
