It sounds like your hammer strut missed the opening of the main spring. It takes a couple times to get the hang of it.....
IF YOU HAVE DIFFICULTY REASSEMBLING THE PISTOL,
HERE ARE SOME HELPFUL TIPS!
If the hammer strut does not contact the plunger inside the mainspring
housing as it is swung shut, it will either be impossible to close the housing, or
the housing will close but the bolt cannot be fully opened without binding.
Make sure strut is free, hammer is uncocked, and repeat steps 6-11, above.
If the mainspring housing pulls out of the gun when swung in, the barrel/
receiver assembly is not fully rearward on the frame. Repeat step 3, above.
Remember that it is essential that the hammer must be in its vertical,
uncocked, position as the mainspring housing is swung shut. If the housing is
excessively difficult to close, the hammer is probably cocked. Repeat steps 7-12,
above.
The foregoing may give the impression that reassembly is difficult, but it is
quickly and easily done once properly learned.
I don't have one anymore, but I remember having the same issues. I doubt you hurt anything.
Good luck.
