It would make me think that something is goofy with the firing pin block lifter or it spring or a broken tip off the firing pin. If you take the slide off ,remove the barrel then lay the slide upside down. next thing is to push down on the firing pin lifter block. It is close to the back edge of the slide and is spring loaded. While holding the lifter block down with a small punch use another punch and push inward on the back of the firing pin. With the lifter block pushed down that gives the firing pin clearance to move forward to strike the primer. So you should be able to see the tip of the firing pin protrude out of the breech face.
Are those pin block 80 series style guns?????
