Hello All - REMARKABLE totally helped me with this. My trigger system was totally jammed - due to my stupidity- I did everything wrong.. and paid the price .. I needed to remove the steel locking plate (held in by the plastic locking block on the floor of the receiver) & once out, I could manually press in the firing pin hammers manually. Once that was done, I could muscle the trigger group back into position and lock it back into normal position.. it does take some pressure, but nothing violent. Very happy for the support and guidance.
