Possible PKM improvement - use of a Side Hammer and Striker Plate?
I am researching an improved design for my PKM trigger group.
I have planned to build what I would call a "swing hammer" or a "side hammer" that contacts a striker plate which in turn touches the firing pin. In my mind I see an old-time howitzer breech where they close the door, and someone pulls on the rope attached to a striker to hit the primer. Along those lines, put the "striker plate" over the firing pin, and instead of a rope (:) ) put a hammer.
The beauty of this is that the room behind the carrier, and in front of the back end of the PKM receiver (when the carrier is in battery) will let me put a hammer "beside" the carrier so that I can modify AK parts. :brows:
Another advantage is that since this is not based on the M60 semi-only conversion, it will not need a tube for the striker. Which is OK for a fixed stock, but on the skeleton stock of a PKM the tube is exposed (as is the case with the one commercial design I've seen).
It appears that Swiss use the side hammer design with a striker plate or transfer arm on at least one of their designs. I think it is the STG-57, but I can't be sure.
Can someone enlighten me on the Swiss design? I've looked around and can't find good information about the action.
