    SIG 228 Roll Pin Question

    I have a W. German SIG 228, and about every 300 rounds the roll pin retaining the firing pin in the slide (unsure of the exact name) starts to walk out of the slide; this is obviously unsatisfactory.

    I'm curious what tool(s) I need to replace that dual roll pin setup, and the exact procedure involved.

    Thanks!

    A roll pin punch and hammer is all you need.

    Try this setup from Grainger. Notice the pin punches have a "tit" on the end to keep the punch from slipping off and deforming the pin or damaging the gun. This of course will not work on solid pins. Here is a link in the right direction.

    It is also helpful to have either a non-marring spacer with a hole in it for when you drive the pins through the slide or a hole pre-drilled in your work bench. There is a gun smith's block for this purpose that is made of hard rubber and in the old ARS "Gunplumber" video, Mark Graham made one out of a hockey puck. FWIW, a block of wood or a sturdy plastic ammo box will work almost as well.

    You drive the old pins out as one unit. To install the new one, start with the outer pin. Orient the gap to 12:00. Get it barely started and then stop. Push the firing pin forward then drive the big pin in half way. Next, start the small pin in, orienting its gap to 6:00. Drive the small pin in until it's flush with the outer. Finish by driving the two pins flush together.

    Be careful about the start, you can damage the firing pin if you don't push it forward.

    Thank you both. Great info. The package of parts from Top Gun Supply should be here tomorrow. If I get stuck I'll be back with more questions.

    Depending on where the old pin broke this can be an issue during the removal process too. On one occasion, I spent some time tapping away only to realize half the positioning pin was hitting the firing pin.

    Does anyone know the proper name for the pin in question?
