LD13 yes, I did switch the stocks but I have used both stocks and barrel combos previously with no problems. I have it stripped down to the bare reciever now and something is wrong. I need to take it apart to see if something has come loose such as the hammer spring, or maybe something broke. I might just start pushing pins out and just see how it all goes. I am not very good at reading parts diagrams but have looked at the one Graybeard put in the FAQ sticky above, but when I tried to open it up and study it again the pic wouldn't open so I am having all sorts of luck.
