    I just bought a S&W 638. It has an Integral front sight held in with a roll pin.

    I want to put a XS Big Dot of the front sight.

    From what I can tell the sight comes without a hole drilled in it.

    http://www.gunblast.com/XS_BigDot.htm

    The above site explains how to install it.

    I am a little worried about wollowing out the roll pin hole if I use it as a guide to drill the sight in position.

    Has anyone installed this sight and is that how it is done? Use the roll pin hole as a guide? Or should I punch it and take it out and drill it?

    Or I was one page said to use glue? I'm a little scepitcal about gluing it in place......does not seem like the way to go.

    Thanks

    Maybe I should repost in the GNG Lounge?
