    Those 'Pesky' Front Sights (staked)

    A quick way to install a front sight with a 'tenon' ,,,,,,,

    Remove the front sight, if it exists, and grind a shallow recess where the new tenon will protrude inside the slide. Be sure to make the recess diameter wide enough for the peened material to have space to spread into.

    With the new sight in the jig you can peen the new tenon to fill the 'recess' ,,,,,,,, the jig serves to 'back up' the top of the front sight while peening.

    Nice fixture and photos.

    Is there a provision for adjusting the angle of the slide, and therefore the sight top, with respect to the fixture backup surface?

    I rest the sight top on a 10 lb steel block, and clamp the slide in a machine vise to hold everything at the proper angle. With the sight top and backup surface exposed, it is easy to ensure that the sight top is in firm and complete contact with the steel block. This prevents deformation of the front or rear edges of the sight top.

    Thank you.

    The fixture has a small threaded clamp that holds the slide tight against the jig with the sight resting in the groove. You can adjust the slide angle by placing a shim(s) near the rear of the jig. Also, I place a narrow piece of brass shim stock in the sight groove to protect the top of the sight while being peened.

    The clamp is a nice feature. Parts that are in perfect mating contact have a tendency to bounce under impact.

    I have to hold the slide firmly against the backup block while staking. Not a real problem, as this also serves to steady the staking tool.
