I just inherited a Mark 1 (A-100 grip frame) from my father-in-law and I can't get the dang thing disassembled for cleaning. The mainspring housing will swing out of the grip frame, but I can't get it removed completely. I made sure the hammer was not cocked, and I've tried tapping on the top of the bolt stop pin with a mallet will pulling down, as per the instructions. The pin will move up and down about 1/16 - 1/8 of an inch, but I can't withdraw it completely.
After trying this for about 10 minutes, I went ahead and closed the mainspring housing back up, and now the bolt won't cycle. It will only move back about 1/2 inch. Before, it would cycle, but felt really dry and gritty.
It is pretty clear from the condition of this pistol that is has not been fired or cleaned in several years. Based on the S/N, this pistol was made in 1981. Any guidance would be appreciated!
