Does the henning cone fit guide rod fit in the witness p 10mm. also what other henning parts work or can be easily adapted to work in my new handgun. I intend to mainly feed this pistol loads on the warmer side (double tap, underwood, and handloads). i have already aquired the wolff recoil spring kit and would like to make any other neccesary modifications to ensure a long service life. any suggestions would be greatly appeciated.
