The only difference now is if the left side plate doesn't come off easily, than you will have to take off the right side plate and through the screw hole use a 1/8" straight punch and put it in the hole and lightly tap the left side plate off. Take your time no big deal and when the left side plate is off you can use the same punch and push the firing pin out from the breech side. This will also give you a good look if there is any crud behind the side plates that can be cleaned with a tooth brush and some good cleaner.
