I'll admit I'm not that familiar with the post war solid frame I.J.s; does the hammer rebound after firing? I don't see any parts in the schematic that look like they'd provide a rebound function.
If the hammer does not
rebound after firing, then you'd need to hold the hammer back a little when removing and replacing the cylinder to keep it from catching on the firing pin.
Maybe the half-cock notch on the hammer is worn or chipped off.
