It is a fairly simple operation to remove the mag. disconnect. I had a hard time getting the taper pin out and ended up buggering up the frame on my Mk.III, but hey, just the excuse I needed to have it hard chromed!
Good info on this can be found on the Unofficial Hi Power Forum, or just ask Stephen Camp. His replies are gold.
Well I finally got it removed.Reinstalling the trigger was a little tricky though.The trigger pull is still very heavy,maybe it will get better after I shoot it some.Next on the list is to bob the hammer and install a single extended thumb safety.
