Bryan,

Which dash number is your 686? I ask because the firing pin I spoke of works only with -5 and newer. Dash 4 and older have the hammer-mounted pin.

If you get the pin, you may find that it doesn't retract far enough without filing the forward edge of the retaining slot. I think the instructions mention this also, as I recall.

You also may want to check out a company called Apex(I believe). I'm told that they also make an extended pin.

Let us know if there are more questions.
Andy
