Depends in the diameter of the firing pin. If the parts are more recent manufacture, no. You should verify and if needed reset/adjust the firing pin protrusion to .035"-.044". My preference is to only adjust the firing pin stop when doing this. Any other adjustment on the other end is not recommended or needed.
